I reverted back to Plex for Android 8.11.0 (post link) so that I have the ability to turn off the “Enable New Video Player” not the “Enhanced Video Player” that I presumed earlier.
I accomplished this by
- Turning off automatic updates
- Uninstalling Plex
- Installing Downloader by AFTV and Sideloading the Amazon Fire OS Devices (armv7a) apk in from the post linked above.
- Use the Amazon Fire TV app to cut and past links into the FireTV gui.
- Once installed go to Settings → Advanced → Set the Enable new video player to OFF
I look forward to @Plexinfo fixing this issue and allowing us to update our installed application for the full experience as well as security of our devices.
Here are screenshots of the menu and setting.
