Hi, @bookedmedia
Welcome to the Roku Community.
We see that you are having troubles with the CalendarStream app on your Roku TV, and we're here to assist. We recommend performing a troubleshooting step to successfully setup the app on your Roku TV. Kindly follow the instructions below:
- Navigate to the channel tile on the Roku home screen, press the star (*) key on your remote, and choose "Remove channel".
- Next, restart your device from Settings > System > Power > System Restart (If you do not see a Power submenu, skip to the next step).
- Once your player/TV starts up again, go to "Streaming Store" on the Home screen, and add the channel back once more.
- You may also refer to this link: How to resolve a channel playback issue | Official Roku Support
We hope this works. Let us know if you still face the same issue after performing the steps above so we can continue to assist you.
Best wishes,
Kash
