Closing the game on Android doesn't properly disconnect the client

[SubatomicPlanets]

Description

On Android, when quitting the app, the server and other players don't get notified. Eventually it will time out due to heartbeats, but that is not ideal. When quitting the game on other platforms, such as Windows, it correctly notifies the server, and the player prefab gets destroyed.

Environment

• OS: Android
• Unity Version: 6000.0.25f1
• Netcode Version: 2.1.1

Additional Context

Specifically tested on:

• Samsung galaxy J5 2017
• Meta quest 2

As far as I know, this is a limitation of mobile operation systems, android will instantly freeze the app when put in the background and will terminate the process nearly instantly as well when the user closes the app.
I'm interested if there is a workaround for this tho.

We're also seeing this, which causes players to persist in the lobby indefinitely and blocks them from rejoining for some time.

Meta Quest 3

Would love to have a solution/workaround for this too
