Molly does not receive generic notifications in the locked encrypted state

[gcvl]

Hi!
Molly (the Signal fork) has a database encryption feature which allows to receive a generic notification even when the app is locked. Now, while normal notifications - with the database encryption OFF - are perfectly fine, that specific option doesn't work at all with the latest microG 0.3.10.250932.
On GrapheneOS with Sandboxed Play Services it's flawless, so here microG must be the culprit.

To Reproduce
Steps to reproduce the behavior:

1. Molly / Settings/ Privacy
2. Enable Database Encryption.
3. Lock the app

Expected behavior
A generic notification (no sender's names, no content) should show up everytime a message or a lost call is received by Molly in the locked encrypted state but nothing happens.

System
Android Version: 16
Custom ROM: LineageOS 23

• Did you enable the setting to notify on new activity when locked in Molly?
• Is Molly configured to use FCM as push notification delivery service?
• Does Molly show as registered for push notifications in microG Settings?
• Does the push notification message counter in microG Settings increase when receiving messages?

Hi Marvin, yes to all your questions!
