I just got a 5.1.2 soundbar system that supports Dolby Atmos. I’ve already confirmed it just works on Netflix. When I try to play content on Disney+ that says it has Atmos available in the details, I still only get Dolby Digital Plus 5.1. Does Disney just not support Atmos for Android? The app is 2.5.1-rc1.
Atmos currently works on my Philips android via denon receiver.
D+ was broken for a few months with the symptoms you describe. Make sure you’ve updated the app.
Edit: version that works is the same you posted. 2.5.1-rc1
