It didn't used to display an ad for Apple's channels but now it does and it requires the remote to dismiss... Previously you could just blindly airplay something but now you have to airplay + dismiss the ad with the remote.
I’ve been using Apple TV since the first generation and haven’t gotten an ad in my experience - did something change or a new version of the hardware I’ve not noticed yet show up? Are you using the Apple TV app itself?
That sounds horrible and I would immediately quit the ecosystem... I have never experienced this in nearly a decade of use, but I also pay for TV+; is it possible you got the bad luck of getting a terrible A/B test or something?
