MLB App Suddenly not working
Welcome, and thank you for posting here in the Roku Community, SweeneyTodd!
Thanks for reporting this to us. We'd be happy to provide further information regarding this matter.
If the basic troubleshooting steps of removing the app, performing a system reboot, and then reinstalling it don't fix the issue, we highly recommend reaching out to the channel provider themselves for further assistance.
We believe this is related to their new requirements, which may affect some Roku devices. They no longer support a specific Roku device model. Since they manage and maintain their app on the Roku streaming platform, we recommend coordinating this with them.

We hope you find this information helpful.
Warm regards,
Carly
