Cannot complete registration on iPhone

I have my passcode for the app, filled in my personal details address etc then hit continue and get
a message stating that there’s been incredible demand for Revolut recently meaning there’s a short waiting list and that I should enter my email address to get notified, but there is nowhere to input my email address!
I have reinstalled the program but no results.

Which country are you based in?

I am in Australia.

Australia is one of the countries that Revolut will be launching by the end of Q1 2018.

OK great. I though you were operational already.

-Global expansion: US, Australia, Canada, Singapore, Hong Kong (Q1 2018.).

I can not registration my Account! I need the phone number of the support!
