Yesterday it also gave up the ghost for me.
However, the web version works. You can also install it via the desktop manager.
According to support, they are working intensively on the problem. Let's have a look.

Hello,
I'm not entirely sure, but could it be that the file manager suddenly contains an Andres APK version?
Last week it didn't work for me either, then I just installed it again and then it worked again. The message no longer appears. I would have to test again today or tomorrow.

Hello
Why will it stop working from then on? I thought the problem would be solved rather than made worse...
Chromcast or Amazon Stick seem the most favourable options. But actually a nonsense to double the whole Android TV. Apple TV therefore actually stupid too.
