Netflix buffers/freezes

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.
