I have been having the same problem. What is weird is that the commercials are in sync, but once the court coverage comes on, it’s out of sync. It is corrected by going out of the app and reconnecting, but as soon as a commercial plays (in sync) and the court play resumes, it is once again out of sync. Going in and out of the app on every commercial break is tedious and there has to be a better solution. Help!
When out of sync, push button on remote that looks like circle with arrow pointing down. I think it backs it up 10 sec, but then it's in sync.
Thanks for posting here in the Roku Community, @Dondemus!
