I've had the same using Edge but seems OK on Chrome which would indicate more a browser compatibility issue than it being a UK issue -or is that over simplifying things??
still freezing up and can't view cams - if as Georgia indicated to me you know what is causing this then surely remove the issue while you work on it so we at least have a useable platform during these changes. Otherwise I suspect the numbers here will dwindle - its not like 100's are ever on chat!
