bebowilson thanks Bebowilson, I assumed I wasn't the only person here who uses Netflix but wanted to confirm. I will spinup my Monterey test installation (and then if necessary create a Sonoma installation) to test further. It would be weird if Netflix didn't like Orion/{Mojave/Catalina} but was fine with Orion/Sonoma, etc.
QQ if you know offhand -- are you streaming at 1080p and/or 4K through Orion? Or does Netflix downgrade you to 720p since you aren't on "the real Safari" (or Chrome)?
