I'm also having the same issue with Acorn TV thru Roku. Started a day or two ago. Happens frequently between episodes of the same show. And I'm streaming from only one device!
Happening to me as well, while using a streaming device on one TV, and also when watching a Roku TV...all while watching BritBox...tried all of the above that the rest of us have tried. To no avail. Where and when will Roku address the issue and will the premium channels discount the days and episodes we've been missing? Extremely annoying is right. Anyone successful in removing the message yet? So far no compromise of the account that I can see. Looks like it could be a hack/glitch, as well all started having the problem yesterday.
