The problem should be fixed on the latest beta (v8.26) you can find them on our beta release notes thread; Release Announcements - Android TV beta - #484 by sixones
If that doesnt solve the issue for you, you can try this build which applies a fix for Google TV devices to all devices: https://artifacts.plex.tv/android-experimental/8.27.0.29135-71a6d4f5/PlexForAndroid-8.27.0.29135-71a6d4f5-Armv7aGooglePlayStdExo.apk
The Google vs Amazon part of the build doesn’t matter for TV devices as we don’t use the billing platforms on TV.
