When trying to play enhanced and when trying to watch the MotoGP of France from the MotoGP page, I get 'We are unable to detect your account'. It works ok for Standard player or if I try to play older MotoGP races. I can watch the French race on my phone.
We're investigating why a small number of users are seeing that message. Logs suggest that logging out and logging in again should fix it (or clear your browser cookies).
I have tried both those things with no success.
