Huh. They worked okay for me - even switching between streams to test if they were working... and most were fine (occasional refresh, and nizarstream plus a couple of others did require a VPN set outside the UK).
I had uBlock Origin running, with the antivirus temporarily disabled until the stream appears - and all is good. An old Windows 10 PC, nothing special specs or graphics-wise. Frustrating to see many are having issues of late - hope that changes soon for anyone having problems getting a decent stream
