Hi @GregR66,
A warm welcome here in the Roku Community!
We're glad to assist you with your problem with the Sling TV app. What Roku device are you using right now? (e.g., Roku Express, Roku Streambar, Roku TV; specify TV) Are you getting any error messages or error codes? In some cases, removing the channel and then reinstalling it may help. Please follow the steps below:
- Remove the channel: Highlight the channel tile on your home screen and press the Star button to open the options menu. Select Remove channel and confirm.
- Restart your Roku device: Restart your device from Settings > System > Power > System Restart (if you do not see a Power submenu, skip to the next step).
- Re-install the channel: After your Roku device restarts, visit the Roku Channel Store or Search and add the channel again.
Let us know if this works for you.
Best regards,
Eunice
