I have subscribed to a channel called NFHS. It says I'm subscribed through March 2, 2021. When i go to watch it, it tells me I need to subscribe. When I click on Subscribe, i get a Roku popup that says I'm already subscribed to this channel. The popup then says, "Please sign in to this channel to start streaming." So I just keep go around in circles. Is there some "sign-in" place I need to go to.
