Due to rules imposed by Apple and Google, it's not possible to create the account within the app. Follow the process on the web site, and you'll then be able to use the account in the app.
Thanks. I did try and register on the web site but there is no facility to do so. I'm wondering if it is only available when the event is actually listed on the website? I cannot find any link to creating an account, only logging in.
Correct @Bazza66 - you need to wait for the event to be available to buy. You'll be able to create the account as part of the order journey. Currently only UFC 254 is available for order.
