onUserOffline No callback triggered

[mzyisbest]

I'm on a call between ios and android. During the call, the ios side kills the process, and the other side's Android side has a callback onUserOffline.
But when android kills the process, there is no callback on onUserOffline on the IOS side.

@mzyisbest This is due to system differences. When a user on the Android platform leaves, other users may receive the onUserOffline notification relatively slowly.

@guoxianzhe The callback hasn't been triggered yet, it's not slow

@mzyisbest @liylmn Maybe triggers "timeout offline". If the user does not receive any data packets from the other party within a certain time frame (20 seconds for communication scenarios, slightly delayed for live scenarios), it is determined that the other party is offline. In case of poor network conditions, there is a possibility of false alarms. It is recommended to use the Netease Signaling SDK for reliable offline detection.
