STIRR will have to update their channel to work with Roku OS 11. Do all your other channels work properly? Reach out to Sinclair Broadcast Group and let them know what’s going on. They develop the channel
I have done that! Also having a problem with Free to View Tv keeps telling me channel is temporarily unavailable due to slow internet connection . but my internet is at 560 contacted the owner of that app and evrything is fine on his end. Just kinda strange that i started to have problems when Roku rolled back my update
Please be aware that the latest OS 11.0 build 4193 is not a downgrade, as it is the most recent OS release.
Try removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more. Does this clear up the issue you are seeing?
In addition, have have you checked for a channel update to see if the channel current?
For more information about that channel's features and functionality, you'll want to contact the channel provider support directly to inquire further. Many channels on Roku are developed and maintained by the channel provider themselves.
