I launched the app, waited for a few minutes, and then resumed it.

Additional Information

I discovered that the connectGuestUser function calls logOut first. As a result, ConnectionRecoveryHandler.stop is invoked, causing the monitoring of appDidBecomeActive and appDidEnterBackground to stop. This leads to the issue where "the WebSocket does not reconnect when the app resumes from the background.

This issue reliably reproduces with a guest user, but it is likely to occur under any condition where logOutFirst is true.

Hi @masarusanjp, thanks for spotting this issue!

The actual issue is that when reconnecting, logOut should not be happening, so the logic should be changed here. Stopping the recovery handler on logout is something that we want, but it caused this unwanted side effect due to the fact that logOutFirst in guest user is not properly implemented it seems.

We will pan this fix, and we will let you know once we start working on it. At the moment we do not have an ETA on when this will be fixed.

Best,
Nuno

Hi @nuno-vieira, does this only affect guest user? or all user?
