Last week the CBS channel worked fine, but now it's not working at all. I've uninstalled it and reinstalled on 3 different Roku boxes. The channel comes on, but after you select a TV show it crashes and goes back to the home screen.
To ensure the process of removing and re-adding the CBS channel is successful, make sure to restart your device before adding the channel back in. from the Settings menu by navigating to Settings > System > System restart > Restart. However, if it still has no dice and the issue is only with the channel alone, this is a good indication that there is likely an issue within that specific channel that will need to be addressed with an update from the channel publisher. Channels on Roku are created and maintained by each channel publisher. In this case, you'll want to reach out to CBS support directly to share your feedback.
