When the client is inactive for some time (a few hours a day?) and I open the app again, it reconnects too all accounts and shows as online for all accounts.

It also shows the MUC room chat as online (with green dot) but does not load any new messages to the MUC chat and also when I try to send anything like "test" to the room, nothing is really sent.

Only after I kill the app and start it again it reconnects to all accounts and to the MUC room correctly. It loads all new messages to the room and allows me to send a new message as well.
