Hmmm. That’s weird. I thought it might be related to what @humorkritik experienced, he couldn’t use any of his buttons anymore…
@humorkritik did it start with only one button not working?
@a_bet I think the best case in your situation would be if it was a software problem and somehow the OS got messed up. Then a hard reset should do it. If this doesn’t resolve your issue, you should contact support directly. Let us know anyways.
