When the error happens, does the UI freeze in any way?
Not really : all the menus and buttons are working, but they have no action.
When you say that you need to kill the task, does that mean you can’t exit Podium normally?
Yes.
That must mean that the power button remains lit, even if you try to disable it?
No, the power button is alternately turned off and on when I click on it, it can be disabled, but Podium continues to play !
