Thank you for the answers so far!
Suddenly there was an update on aptoid store which works. So for the moment I can use the app again. But I think we will loose more app support over time and the only good solution is like @dragos said, an external hdmi streaming stick.
I already have a Bluetooth transmitter attached to get my playstation sound on a Bluetooth speaker. Now a HDMI streaming stick and the power supply makes the whole setup look like a hack. Not smart but I think that’s the best solution.
I will also look for an android TV stick. But first I want to be sure that it can support stadia. I bought a premier edition and really like it.
