OK, so this is embarrassing. Time for a little humility. I selected to watch my show via the Roku logo vs the Britbox logo. If you do it that way, you get commercials. I got turned around, as the show had completely disappeared from "continue watching" or any other heading. I had to "search", then have to be careful which way you select to watch. -- Confusing to say the least...
Alrighty then, hope this is helpful to anyone that this may have happened to LOL
Cheers - 'till next time
