Steps to reproduce the bug

Steps to reproduce:

1. Open app and navigate to a conversation.
2. Leave the app, but also leave it open. Pressing the android home button works for me.
3. Leave the phone charging overnight. (Or some other way to cause android to cache the app to storage instead of ram)
4. Open the app. It will still be in that same conversstion view(as expected).
5. Press the back button.

Expected behavior

The back button should always navigate to the conversation screen from a specific conversation view, instead of only mostly doing that.

Actual behavior

Pressing the android back button will close the app, instead of navigating to the conversation menu screen. I have to reopen the app after that in order to get to the conversation screen.

Screenshots/Screen recordings

No response

Additional information

The bug only seems to show up if the app has been cached by android while open in a conversation view.

There is no issue when i leave the conversation menu open and leave the app alone for a couple hours.
