My Interlagos Early Access didn't work in Real Racing 3

I bought the Interlagos Early Access pass for £20 when it first came out and was excited to play it.

I instantly fully upgraded the car and completed stage 1 but straight after my game crashed. After loading it back up I tried to access the event.

As you can see in the attachment I was pressing continue but nothing happened I do have a video of this but it won't let me upload an mp4.

The event is now over so I hope I don't lose the chance to earn the rewards (gold, M$, the car etc.) especially because I paid £20 for it and I didn't even get to drive the Interlagos track at all other than the first stage.
