Welcome to the Roku Community!
Thank you for reaching out about the issues you are experiencing with your Roku Ultra apps. I'm here to help!
Could you please specify which apps are experiencing problems? Also, provide the OS version of your Roku device by navigating to Settings > System > About.
I highly recommend restarting the system. To do this, navigate to Settings > System > Power (if you do not see a Power submenu, skip this step) > System restart.
For detailed instructions, please refer to this support link: How do I resolve channel playback issues?
Let us know if you notice any changes afterward.
Thanks,
The Roku Community Team
