Interlagos

INTERLAGOS INTERLUDE IS NOT WORKING 

It's been 2 weeks since this started, there has not been a patch or anything to fix it, I haven't received any refund. After going back and forth on the help chat for 2 weeks with no resolution, they told me to post it on the forum. I purchased the early access to Interlagos Interlude, after completing all the way to stage 4, it locked me out and it's not letting me do the final stage. I know another players have this same issue. By any chance, have you found a way to solve the issue? There's only 3 days left on the event and I don't feel it's fair.
