If you have not yet created a UDisc account, your UDisc Pro upgrade will not take effect until you do. Tapping Profile in this state should allow you to create a new account.

If you are unable to create an account or creating an account did not solve the problem, please email a copy of your receipt and your UDisc username to help@udisc.com and we will get you sorted out as quickly as possible. Your UDisc username is shown at the top of your screen when you go to the Profile tab.

Android: Locating your Play Store receipt.

iOS: Finding your App Store receipt.
