My Roku player is froze and defaults to Disney plus . tried resetting it . bedroom box works in there . tried the bedroom box in my living room does the same thing do you think I need a new TV ?
Try unplugging all devices (Rokus/TVs/etc) for 5-10 minutes and see if that resolves the issue.
You didnt mention your Roku's model #s or firmware version (Settings/System/About) or app version (highlight the app and press Options (*) on the remote).
FYI, the Disney+ app updated yesterday (8/5) to version 1.15.2021080400.
Try reinstalling Disney+:
1) Remove the app (Highlight the app, press the Options (*) button on the remote, then Remove)
2) RESTART the Roku (Settings/System/System restart/Restart) <-- MUST DO THIS HERE!!!
3) Re-install the app
(If you dont restart, settings/cached data associated with the app are left behind and it wont be a clean re-install)
