Guessing Roku4 hardware or HDCP software isn’t up to snuff for Apple. It’s a farce that it’s even available on Roku in the first place but the profitability was too hard to ignore for Apple. They will likely never play well together. Pulling the networks apart as apps has been horrific for end users and large MSO apps are really bad too. Money and/or franchise rights are making the sea change in TV set top boxes quite the sh!t show.
