If its telling you it cant display due to region. That is the reason to use a vpn.
I dont know why it would if you live in the states. But i do know a vpn can solve your issue.
I can only see fight pass on my computer when I try to see on my smart tv it says '' fight pass content is blocked in your region '' but I'm located in the Us it's very frustrating I tried contacting Ufc but they have Shxxty customer service anyone else had problems with fight pass? I tried deleting the tv app then reinstall but if I can't get the problem fixed I'ma cancel it.
