Netflix Poor Resolution

I recently switched back from DNSFilter to NextDNS.  I have EDNS client subnet option enabled as well as cache boost enabled.

Since changing my DNS to NextDNS, Netflix has started having streaming issues.  The quality is initially fine, but after a while it gets pixelated as if I'm on a 1 Mbps connection.  I had the same problem last year when I was using NextDNS.  This went away with moving to DNSFilter last year, and it stopped doing it again when I changed back to DNSFilter.

Does anyone have any tips how to fix this or has anyone experienced this before?  It seems too coincidental that over the last 9 months I've been using DNSFilter, I never had a problem with this.  4 hours after switching back to NextDNS it returns.

Thanks for any help anyone can provide!
