A warm welcome here in the Roku Community, @mnmdaly.
We appreciate you reaching out for support and we'd be more than happy to assist you in accessing the Apple TV channel on your Roku Ultra.
We may need to reset your PIN first to be able to re-install it. Kindly sign into your Roku account > PIN Preference > Update. After doing so, kindly follow the troubleshooting steps below to help you access it:
- Remove app: navigate to your Home screen, move to the right, highlight the app, press Star*, then select Remove channel
- Perform a system reboot: navigate to your Home, select Settings > System > Power (skip if unavailable) > System restart
- Re-install the app: navigate to your Home, scroll and select Store, look for the app, then press Add channel
Please make sure that the steps have been performed precisely to work.
Let us know how it goes and we'll continue assisting you from there.
Best regards,
Carly
