Help & troubleshooting for channels on your Roku device, including adding/removing channels, logging in to, authenticating, or activating a channel, channel-specific playback issues, assistance contacting channel publishers to report issues, and adjusting channel-specific settings.
What Software Version do you have on the devices where it works from Settings->System->About? If it's 9.2 on the working devices then there's your problem. You'd have to contact the developer and let them know there's a problem with their channel and v9.3.
@Loucovey thank you so very much. This fixed the issue!! I am so happy, I was worried I made a bad purchase. I spent so much time doing troubleshooting steps, removing and reading channels, this literally took 2 minutes (if that) and completely resolved it. You are officially my hero. But my family thinks that I am techsavy now, I will go ahead and let them think that. Thanks again.
@blancas my Roku doesn't have a sd card slot. Just highly annoyed.
Does that mean it has to so with space issue? I haven't added any more channels than I have always had so confused as to how space would be an issue? Did you move some channels onto the SD? It says a SD card is not actually required so totally confused.
