Yeah this is frustrating. If they fixed this, had Apple+ and fixed the lip sync issues with Dolby output on my Sonos Arc when using external devices I’d be very happyYep that's still an issue for me too. Not sure it's as easily(!) solvable though, because you can't actually uninstall the Prime app as far as I can tell; it's baked in. You do have the option to restore it back to the factory-installed version, but that hasn't solved the issue for me. Even though it shows the HDR symbol next to a programme, the TV doesn't switch to HDR mode when you set it playing.
