How do you change the audio language for the Amazon Prime App on Apple TV?

Hi,

I’ve just started using Amazon Prime on a 3rd Gen Apple TV. I’ve watched one episode of the German production 4Blocks which played in German of course and this is what I wanted. However the 2nd episode changed to Italian and I can not find a way to change it back to German. I’ve looked at the Amazon Prime’s help pages, but the settings they suggest to use just don’t exist. I think at one stage I got sent to Apple support, so I knows where this often leads...the endless loop between Apple and Amazon etc...

Can anyone please give me a tip in case I’m just missing something or perhaps try to change the audio language if you’ve got Amazon Prime and tell me how you went.

Thanks in advance for any help you can give.
