Closing the game on Android doesn't properly disconnect the client #3119

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.
