I can't remove the app and reinstall it - I have to cancel my subscription in order to remove it, and I don't want to risk losing my lists. Any ideas?
It has been reported that you can remove a channel app without canceling your through-Roku subscription to it via the official Roku remote app on an Android/iOS phone/tablet. This allows you to use the remove/restart/reinstall procedure used for other channels that are not subscribed through Roku.
Load up the app and be sure it is connected to your account. At the bottom of the first screen, click Search and do a search for the installed channel name. On the resulting screen you should get options to Launch the channel on your Roku, or Remove the channel.
I can confirm that you can uninstall a channel app in this way, but I have not had any subscriptions through Roku in years so I cannot confirm from my own experience that that leaves a through-Roku subscription in place, but others have reported it does.
