I've been watching "Line of Duty" on Britbox through The Roku Channel. Up until now, through seasons 1-3 I have never seen a commercial. However this evening, during season 4, episode 3, I began seeing commercials for Paramount+ on The Roku Channel. During this episode and subsequent episodes I've been seeing multiple commercials either 1min or 30secs in length. Obviously this is some kind of bug. But I power cycled my Roku Ultra and these unrelated commercials are still showing even after restart. What in the world is going on?
