Some notifications are delayed until the screen is on

[frantsy]

Some apps' notification are not received when my screen is off. Once I wake up my phone, the messages are then received and shown. It works ok though for apps like WhatsApp, Message, Email.
I've checked all the battery optimization settings for those affected apps but had no clues why they are not working the way they should. These apps are working fine in my other devices.
Also tried to turn off Adaptive Notifcation, still the same.
Appreciate any suggetsions.

Same problem here. It's quite annoying. Please fix it asap!

Same issue here. System mode is on "Dynamic", disabled any other battery saving feature.
I managed to get notifications working on time (and vibrating, which appears to be both a setting in the app and in Android, for this app) for a reminder app. Took a long time to figure it out and several settings to be changed (such as disabling battery optimization for this app...).
It cannot be normal that one has to do this for every app that send out notifications? Never had an issue with this on my old phones. No "battery optimization" or any other settings and notifications worked like a charm, without battery drain...

I'm experiencing same issues. Thinking about returning the phone.
