Amazon Fire TV Stick

Amazon Fire TV Stick
I bought the Fire Stick. Netflix and DAZN works. BUT I CANNOT watch Amazon Prime on it - it always gets error code 5505. This is despite the fact that I subscribe to Amazon Prime and it works flawlessly on Apple TV and with the Android app - anywhere in the world. Find the error... I thought it might have something to do with the language. You can select "German (Germany)" and "German (Austria)".... I can't enter the postcode for the location either. Does anyone have an idea what I'm doing wrong?
