It happens when ever I try watch anything on demand. Customer service have told me to turn it off and on. That is a temporary fix. They have also said they have sent a signal down the line to fix it. They have also said there is a known issue in my area that they are trying to fix.
i can’t find any mention of hdcp in the manual. It’s a 2020 Samsung so I am assuming it is hdcp 2.2. However I will try the settings you suggested. I will have to do it later this evening though as I have had it unplugged over night, so it should be temporarily working at the moment
