I would like to add a disconnection handler to make it later when new radar is finished.

disconnection handler

What do you mean by that?
Else I think this issue can be closed by now as if a map-style is not available always the fist style will be used as fallback.

Instead of directly closing the connection when wifi is disconnected or have any disconnection with server we try to reconnect e.g wait every 5m to try to reconnect and have a max attemp if falied then close connection else instead lf generating nee session it will use the same version. What do y think abt this feature?
