Thanks for letting us know about the issue with the apps on your Roku device. We're here to help!
Give this a try: Remove and Reinstall the app. Often, that can clear up the problem. Restarting your Roku device (Go to Settings > System > Power, then select System Restart) before adding the app back can also help make sure everything goes smoothly.
Let us know how it works out!
