Since the last update Netflix often seems to have issues with the buffer in that every several minutes it will pause video and just play audio then either jerkily run a little catchup/resync , or will freeze entirely. This does not happen with Chrome. e.g. I can be watching with Brave, and I will get freezes every 2-3 mins, switch to Chrome no freezes, switch back to Brave and get freezes. Brave is the latest version. Win 7x64 if that makes a difference.
BTW, Amazon Prime still does not play 1080p, though it does not freeze, but plays 1080p on Chrome, due to “content restrictions”, not that anyone has responded to that thread either.
