I'm experiencing the same thing -- when streaming music from an app, Roku is playing just 2 or 3 songs then pauses. You have to press OK to resume play. This is only happening on Roku, not Apple TV, and has just started in the last couple of weeks.
While using Pelaton app, the workout pauses after a certain amount of time until I hit okay. Then after hitting okay, it occurs repeatedly. What is the solution?
Unless the certain amount of time is four hours, that is within the channel, not the Roku itself. If it's 4 hours, change the bandwidth saver setting mentioned above. If not, it's the Pelaton channel and you'd have to talk to them about it. Roku does not create or maintain channels for other providers.
