Amazon Prime - watching content in HD
Hi. Every time I get a movie to watch on Amazon Prime I get the message HD unavailable, and then a pop-up that says my computer, hardware, HDMI cables and display must all meet content protection (HDCP).
I don't get it - I have a new M1 mac with a 5k Apple Studio display, and all the right original cables. What is going on, and why am I getting this message?
Any help would be really appreciated!
