Welcome to the Roku Community, @TakomaPark!
Thanks for letting us know about the playback issues you're currently experiencing within the CBS app. We'd like to provide further information about this and help you contact the right Support.
Please be informed that certain standalone apps on the Roku streaming platform are being managed and maintained independently by the channel provider, so we highly suggest directly coordinating this with their Support team for further assistance.
You may reach them here: CBS Support | Contact Us
We hope this will be sorted out soon.
Best regards,
Carly
