Background process stops & Notifications are not working on LineageOS (no google servicies)

[ghost]

Describe the bug

Notification are not showing.

To Reproduce

Steps to reproduce the behavior:

1. Setup notifications to "Optimize for real-time", delay sync default 60
2. Battery optimization in Android setting is "Not Optimized" for Element
3. Troubleshooting notifications: all green 8/8
4. When I open the app I see sticky notification "Listening for events"
5. After I scroll the "top menu with notification" over app or I close the app the sticky notification disappears

Expected behavior

I believe the sticky notification should be there all the time to keep background process running. Signal, Telegram and all other apps are doing it this way.

Screenshots

Notification settings:

Sticky notification UP (will disappear shortly, after I close app / keep scrolled top-menu for some time)
