If you already have D+ installed, will you be able to update it after installing the current hotfix? (i.e. what if D+ adds Atmos support in an update before the next Shield general release?)Nothing projector specific but I'd would suggest applying for the Hot fix after you've confirmed that the hardware works. Make sure to install Disney+ app as once applied the Hot fix would prevent it's installation. The warning about not being able to back out of Hotfixes once applied, is specific up until the next general release. After that your back in the standard update release schedule.
