I’m experiencing the same thing. I have all background data settings turned on, battery optimization turned off, notification priority set to Max. No notification sound or visual notification at all. Open the app and the message is there though.

Delta chat is unusable like this.

Hello
I am a huge fan of Delta Chat, use it every day with family since 2018.
Notifications was OK before.

problem : no more notification since version 0.510 (not sure, but i think the problem started with this update).

OS: Lineage OS 14.1
Device : OnePlus X

Same problem for my wife
OS : lineage OS 15.1
Device : OnePlus 3

I hope you can fix it soon because the use of the app is hard without notifications.
Thanks !

Hi there and welcome on board,

there is a open issue already for this:

https://github.com/deltachat/deltachat-android/issues/1008

So I think the devs working on it :+1:

It also doesn’t work on normal Android 9 with Google Apps installed.

the fix was merged yesterday \o.o/
anyone know when new (fixed) version hits the playstore?
