I had real difficulty today to continue with the Raid challenge on the beta platform. TDA did not seem to complete the login fully or on an intermittent basis, so the Premium subscription would disappear and the rides would be locked or even when they unlocked, the ride would not start, as the previous ride could not be retrieved.
Eventually, I did get the ride to start but when I finished it and went to manually restart the next ride, I couldn't restart again.
Has anyone else seen this? Is it individual thing or a more general problem with the servers?
