I see the same problem on commercials. ? Ipads left on the APP for a long time stop responding. ? Some somtimes wake up, but there is a long delay, apx 5 to 10 seconds. ? Others don't. ? Force close and reload is the only way to fix and it works straight away.
never raised with TB, but will do now. ?Do you have a ticket number I can ask them to link it too. ?May e we can add i bit more pressure.
