sideload the Disney plus app. It takes all of about 5 minutes.Also been having minor issues with my set lately. I too don’t have access to D+ app after updating to latest H firmware(not a big deal since I stream from a Shield and never touch the native apps anymore), but in testing I still get audio drops through eARC in those apps. Shield is perfect though.
The real issue I’ve had is that everytime I power on the TV, it takes a few seconds to activate as it reboots Android for whatever reason. Almost everytime I have to wait for the Android refresh to go with the rotating logo and such. Tried a software reset abd that didn’t change anything.
Decided to do the Hard reset with physical power button behind set, which seems to have solved the issue(so far). But D+ still showing as ‘incompatible’ with this set. Bleh.
I may try again as the instructions for hard reset told me to wait a few min for the set to reboot twice on its own before activating and setting up it’s the on-screen guide. Problem is it never activated after the hard reset and after plenty of time passed I powered it on myself and started the process. So maybe something went screwy.
