Element Android App Notification Fix

The Element Android app has been known to stop receiving notifications/messages from other users after Android OS updates. Here's some context and the fix.

Because Element intentionally does not use the standard GCM (Google Cloud Messaging, or now as it's currently called, Firebase Cloud Messaging or FCM) for push notifications, it is necessarily at odds with what the Android OS “wants”, and we, as wise and knowing defectors from what Android “wants” in this case, must configure our software properly. Because Element does not use this method for sending/receiving push notifications to transmit its messages and updates, it is necessary for the Element app to be allowed to run outside Android's Battery Optimization Settings.

Essentially, battery optimization settings needs to be intentionally disabling battery optimizations so that the Element app is allowed to run even when the phone's screen is off, so that it can receive push notifications whenever someone messages you. 

​There is a very handy feature in Element now that can be used to verify/troubleshoot this setting!

• In the upper left-hand-corner of the Element app, select your avatar icon > Settings > Notifications > Troubleshoot Notifications (at the very bottom).
• Take note particularly of the battery optimization check item
  • Change the setting as prompted if it fails the troubleshooting test (and any other things that might influence whether Element works as you'd like/expect).
