Apple tv login problem

Since the last update I always have to enter my password manually. Really annoying because typing with the apple TV remote is ■■■■.

If I don’t do that and just hit the arrow it says: login with this username failed.

Last year I had the same problem with android. That was fixed after an update.

same problem here.
I’ve noticed recently that Zwift always requires me to login on my Apple TV. Has there been a security update recently that requires this? Getting annoying.
