As you may know profiles is now a feature in prime video, I got the updates on my phone and I create another profiles but it hasn't come in the android tv app. There is no way to update directly cause is an app you can't find in play store. The app came by itself with Android 9 update. I'm asking, ¿It exists a way to update to the newest version? Thanks and SFTBE
You could try using Aurora. That can download the latest version from Google Play without having to validate your device.
