I just bought one and the same thing happened after it upgraded to Android 13.

I managed to get it back by clearing the netflix app storage/cache and reinstalling the app.

但只要重新開啟netflix或是重新開機，會再次發生相同的事情，導致需要再次清除 netflix 應用程序存儲/緩存並重新安裝應用程序，非常不方便

Meet the same issue, and I have contacted the ASUS support, but even the support does not know to fix it and ask me to contact with Netflix.😅

Very disappointed.

Reinstall the Netfilx App will not fix this issue as you restart the app, this issue will reappear.

Also, app like Amazon Prime Video doesn't playback in HD
