I have a problem with BritBox on Roku, which began suddenly yesterday. When I try to stream BritBox from my Roku, it asks for a subscription which I already have through prime. Apparently, if I use the Roku channel to bring up BritBox, it thinks I have no subscription. This problem occurs with both smart TVs and both Roku’s that I have. When I stream BritBox via prime on either of my smart TVs or my iPad, it works just fine but if I do it through Roku, it asked for a subscription. This is obviously a Roku problem and not repeat not a BritBox problem advise
