We were watching Winder Woman 1984 on Christmas Day and up popped the dreaded HDCP 2.2 error a total of 4 times throughout the movie. I’ve read virtually every post on here and tried all the support related “solutions” but since the whole point of upgrading to the 4800x was to get Dolby Vision, it make sense to return this and go back to my older box. I’ll still get DV through my AppleTV so that seems like the only solution. Apparently Roku doesn’t monitor these threads nor do they have any direct support for their products, so until they get this worked out I’ll move to a proven stable device in the AppleTV. Good luck to the rest of you.
