Black Friday Event Track

Is anybody else's black friday event track not working? I completely forgot it existed until I got the last chance notification today. It's still showing zero but I've been progressing on the Nordic Nirvana event track. Was I supposed to purchase something to be able to access this feature?

Edit: thank you for the replies! I just started playing earlier this year and this was the first time I've seen a bonus track like this. Google led me here but I was did eventually find the rules for the event through the app 🙂
