DISNEY PLUS NOT WORKING on any of my roku devices. SIMPLY WILL NOT PLAY ONCE IN.

When problems are confined to a particular channel, it may be that the channel didn't install properly, that it didn't update correctly, or that the installation has otherwise gotten corrupted. A reinstall may fix the problem, so give it a try.

Remove/reinstall procedure:

1. Highlight channel on home screen.
2. Press * key on Roku remote and choose "Remove channel "option.[Note: If this is a premium channel to which you subscribed through Roku, "Remove channel" will be replaced by "Manage subscriptions". Click this and follow the prompts to unsubscribe from this channel. (Don't worry. You'll still have use of it for the balance of your pre-paid subscription period. You can resubscribe later if you like.)Now the ”Remove channel" menu item will be back and you can remove the channel. ]
3. IMPORTANT- DON'T SKIP:
   Restart the Roku to clear its memory. Depending on your Roku model and Roku version number you'll find "System restart" under Roku menu path Settings > System > Power or under Settings > System'. Without the restart to clear the memory you may not get a clean reinstall.
4. Reinstall the channel. Note it will be added to the END of the channel grid.
5. If channel requires a login, you may need to log in anew.

When completed you should at least have a clean copy of the app's current release in place.

If the problem persists at this point, it often means the current version of the channel app has a problem that must be addressed by the channel service itself, as they are the ones that create the Roku-compatible version of their app and provide it to Roku.
