Welcome to the Roku Community, @cycle!
Thanks for contacting us and for letting us know about this. We'd like to provide further information about the playback issues you're currently experiencing within the Flo Sports app.
Since most standalone apps on the Roku streaming platform are being managed and maintained by the channel provider independently, we're glad to hear you have coordinated this with their Support team directly.
We also suggest you continue communicating this with them, as they can help you further with this. We hope this will be sorted out soon.
Best regards,
Carly
