I called to cancel my account last week (genuinely wanted to leave), to keep me in they chopped $30 (US keyboard) a month from my account, they now have until start of next season to resolve this issue. On the plus side, it works fine for SPL games........ Hamilton v Motherwell or Man City v PSG mmmm?!
Mine is a Macbook Pro, OS X Yosemite. No error message just would not load TV Anywhere.
My Son's Macbook Air OS X El Capitian, Wouldn't load last night now says - Device not detected.
Although I can now get on to TV anywhere and watch any program. Also in Device settings my son's Mac is registered. (It also states that there was a device change last night at 20.16) We couldn't get on to manage a device????
