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.
Mine did the same today, I went through all the steps, same but only sky News wouldn't work. Checked the update section and there was a firmware update. That fixed it for me. I wish I had checked that First.
I'm having the same problem with one of my Ultras, with the KITV4 app as well. It was working great until last week, and suddenly the app will nor successfully load on this device. It loads on my other Ultra, my TCL/Roku TV, and my Stick, with no issues... but on this one, it simply will not load now.
I have tried the uninstall/reinstall method, the reboot option, the network reset option, and the pull the wire reboot option, switched from Wired to Wireless, Enabled/Disabled Bandwidth Saver, and nothing works...
