Suddenly my ROKU is randomly jumping from the show I am watching in Netflix to the HULU app - suggested as a download (which I do not have or want). While on the “Download HULU app” my ROKU continues to make the sound made when pushing a button (don’t know how to describe it). I see no one else logged into my account. Nor am I near anyone that could be messing with me and changing channels through the window. What’s happening?
