i was having this same problem and i feel it has to do with the memory in the tv if there is such a thing. So i unplugged the internet router for 30 seconds and also unplugged the tv for 30 seconds and started them both back up and so far it resolved the problem.
I had the same problem. I contacted them and was told this is normal even with the bandwidth saver disabled. The only way to stop this is connect a laptop.I left roku in a spare bedroom and connected a laptop to stream non-stop music and movies to the rest of the house. No buffering or pausing.
We have 3 different rokus but only one at a time gets used and while watching a show on Hulu it will pause the show and you must push play to start it. I did the process to disable mobile access so hopefully that will work.
If it's prompting you to ask whether you're still watching that's built into the particular channel/app you're using. There's no global Roku setting for such a thing. You'd have to take it up with the developer of the channel/app.
