Hey there,
I couldnt really find something on the internets regarding my situation.
Some specific keys suddenly stopped working (while playing). And now it seems to stay that way.
I attached an img that shows what keys wont work anymore.
I tried to used different apps, cables and devices to makes sure that the problem is not on the other end.
Tried to update firmware and to factory reset. Not sure if the factory reset worked, however noting changed.
Sorry for my bad English I am not a native speaker.
Best regards
Moritz
