I just updated from a Premier+ which has worked fine for a few years. Simple replacement, unit and power adapter, nothing else was changed.
Now, I'm getting HDCP 020 errors multiple times per hour (Netflix, mostly). Video stops (replaced with some HDCP warning), a brief audio break (<1 sec), and a few seconds later video comes back.
This is customer hostile. I'm just watching streams, not trying to steal content. HDCP is getting in the way - guessing pirates aren't bothered. I don't know what the rules are for HDCP, but it seems Roku needs to do something like - three failures in a row, over more than a minute (I've had error reports and interruptions just seconds apart), before you abuse the customer.
