I am having the same issue regardless of which app is being used. I restarted my device and am still having the same problems. I will click on any app and it will work for about 10 minutes, then kick me back to the home screen.
This is happening to me as well. What you said did not fix the problem. Using Roku stick latest version and a Samsung Smart TV. This only happens with Hulu live and not with Prime or Netflix or any other streaming service I have. At first I thought it was something to do with a timed setting in Hulu that disconnects after a few hours. But I can’t find anything that would indicate this is in fact true. what can I do as sometimes when I start Hulu again there is no audio and I have to turn the TV off, wait and restart the TV. This is not what I’m paying for. Please advise.
