Answer 1

show client detail < mac address while connected to the old ssid>
Try to connect to another ssid and have the following outputs:
debug client
show client detail < mac address > every now and then until the client appear
in the RUN state machine in the debugs output
In the meantime try to disable session timeout on the SSIDs between which the client is trying to change connection.
Also check this caveate which approximately describes similar symptoms:
