Major issue with delayed push notifications - Samsung Galaxy Note 9 Questions & Answers

I have been experiencing delayed notifications on my Note 9, mainly with Facebook Messenger, but it applies also to the Line messenger app and Outlook, so it's not confined to one app. It's probably just that I use Messenger often, so notice it more with Messenger
The symptoms are a random and sometimes very long delay between sending a message and receiving a notification, measured in minutes to hours. Sometimes, I'll receive a bunch of notifications from multiple apps when opening the screen.
Other times, even opening the screen does not cause me to receive notifications. I can be actively using the phone and there will still be a random delay on notifications.
For example, I was using my phone earlier to web browse and my girlfriend sent me a message. I did not get a notification. After 30 minutes, she called and asked me why I was not reading her message. Opening the messenger app, I saw the message there (as well as the time at which it was sent) and about one minute later the notification came in.
Similarly, I can be using the phone and someone will video call me on Messenger. I don't get a notification until I actually open the app (I know this since my other phone that has the Messenger app installed on it rings, so I know I have an incoming call).
I can test notification delay by using one account from a computer to send a message to the account linked to my phone, so I know exactly when the message was sent. But the notification delay, even while using the phone actively, is still present and measured in minutes to hours, whereas the other phone receives the notification immediately.
It is NOT doze mode at fault. I have explicitly disabled ALL battery optimizations as well as turning off doze mode with ADB at boot time.
It's not bluetooth, even though some users in other threads have pointed to bluetooth being at fault.
I have cleared cache, uninstalled all updates for Google Play Services and Google Play and reinstalled them.
The phone itself seems capable of receiving push notifications correctly. I can use the push notification tester app to setup a high priority notification for, let's say 10 minutes from now. Then I shut the screen. After 5 minutes, I send a message to my phone with Facebook Messenger. No notification is received for this message.
After 10 minutes, the Push Notification Tester app triggers its notification correctly, which is received immediately. And then shortly afterwards, the notification comes in from Facebook Messenger.
Clearing cache and data on Messenger doesn't make any difference, and as I said in the first paragraph, it does not appear to be the app, since other apps are affected.
This is driving me crazy. I miss out on messages and important emails.
Is anyone aware of any solution to this problem? I just see a whole bunch of snake oil remedies on the net, but no real solution.
It appears to be something that might be related to notification priority, judging by the behaviour of the Push Notification Tester app, but this is just speculation on my part

Facebook notifications, don't want 'em

How can I tell which application is actually creating notifications from facebook?
In the official facebook app's settings, I've turned off notifications, but I still get them. I also have bloo, and a few other facebook apps installed, but as far as I can tell, none of them are running when I get the notifications.
As they come in fairly often, it can get annoying with the constant buzzing and/or bleeping.
(On a related note: going to the item in the menubar dropdown takes me to the official app, to the notifications page... Which I then close. And then, without any actual new notifications coming in, it alerts me again shortly thereafter. Annoying. Halp!)

Notification Issues (MLB At Bat & CNN)

Hi. Long time iPhone user but new to Android as of two weeks ago. Bought the HTC One (AT&T) and am loving it so far.
However, I have been having issues concerning notifications through a couple apps. Specifically the MLB At Bat app and the CNN app. Let me start by saying that I have received notifications without issue when it comes to email, texts, and Facebook.
Now, with At Bat, I have notifications set up in the settings for the app (specifically for my favorite baseball team), and I technically do get notifications. What I mean by that is, if I happen to turn on my phone, I will see that a notification previously came in. However, I do not receive any audio or vibration feedback to accompany the notification. So, the phone doesn't actually alert me. The same case is true with the CNN app. In the settings for the app, I have set up to receive notifications for breaking news. Again, I technically get the notifications sent to my phone, so they will be there when I happen to check the phone for whatever reason. But when the notification is sent, I am not alerted in any way (no tone or vibration).
As I said before, I get notifications (accompanied with audio tone and vibration) without issue when it comes to emails, texts, and Facebook. I have scowered the system settings and the settings on the individual apps but everything appears to be in order. Thanks in advance for any help or direction you fine folks can provide.
edit: Also, I have uninstalled and reinstalled both apps, but nothing has changed.

Whatsupp queue bug

Hello! I found an unpleasant WhatsApp bug. Using Google Now to send a whatsapp message, is shown correctly on whatsapp but not sent, remains in the "queue" with the clock icon but if you open the application of whatsapp or you get a message from someone at that point is sent, this does not always happen but it happens especially after a few minutes for whatsapp is not opened / used, it seems that the application goes into standby output. Unfortunately this problem limits also the use of whatsapp on a smartwatch Android wear because the response to notifications happens through the voice service of google now.
This happens when you want send new message. Replay always work.

text notifications

I searched Google and seen many with the same issue, but no solution. The issue is getting no text notifications sometimes. I get the text message but no sound or badge number saying a text came in. It's so random I can be texting a person back and fourth. I get 99% of notification a text came in example a sound and visual iindication but a few slip in with out so much of a beep. I did a factory reset, I made messager notification high priority, and I have no other message app. Is it because of Oreo? Is because of Google? Or is just Samsung app broken? No idea, but it kills me.

I've seen the same issue. In addition to pissing me off I have the wife asking why I'm ignoring her messages! I rebooted and that seemed to remove the problem for a large window of time but I've heard of no concrete root cause and solution.

Same here that's why I turned off read notification in messages for TMobile. So the wife does not complain about it.
I read somewhere it might be Google app. I uninstalled updates and disabled it and will report back.
Ok 24 hours later I must say big difference. All text come in and notifications from a Islamic app about prayer times is no longer late. So is it google app? Maybe because I also removed anti virus software. I am add google back on and see what's up.
How sad.... Within 5 mins it started again... It's the google app.
it's usually happen to me when the text app is on-screen, in the foreground. when the app in the background, I get the notification

For me it's both. Phone in my pocket screen off and I get nothing. Only thing that saves me sometimes is my s3 watch. It shows the notification and the phone nothing

Notifications on my Note9 are freaking the hell out

Sporadically since I got the Note9, notifications have been acting up. Today it kicked into overdrive so I'm hoping someone knows what's going on.
For Twitter, I get notifications from specific users that stack in one column in my notifications. I've never had an issue with these, but today, after I tap them and view the tweet, a few seconds later they reappear in the bar like I never accessed them.
Instagram and Facebook keep showing the same notifications, hours after I view them. For instance, a friend posted a picture at 1pm today and I viewed it and the notification disappeared. Then, just now at 4pm, it popped up and notified me about the same picture again, along with 4 others I had viewed/cleared throughout the day. Instagram acts almost identically.
Android Messages will repeat notifications when I open the actual app. So if I receive a text, next time I open the app, that text will pop up as a notification complete with the sound and visuals.
I thought it could be issues with the individual apps, but with the frequency increasing and it happening with multiple apps from different developers I'm thinking it may be the phone or OneUI. Does anyone have any ideas about what could be causing this?
