If you try to access F1TV via a VPN from your country where F1TV Pro is not available (like the UK) it will no longer play the full race videos and displays an geographical error code..
This makes it less convenient to watch F1 with a paying subscription, while they're competing with illegal streaming sites that don't have this restriction.
Please stop shooting yourself in the foot. Fix the terms and contractual mess that burden your paying customer base. They're not the real adversary.
