Thanks @bonnell. I understand that that text can't be changed. I'm done with the integration of Digits to my project.
Ah the issue, I don't have anymore issues, because I'm now "Push"-ing Digits and Digits "Push"-es my next view controller upon success, rather than "Present Modally" the Digits Form at the start and then "Dismiss" when cancelled or success.
I can't provide any screenshots right now, as I don't have time yet -- but if it's really important, I'll find a way. Again, I am using the IQKeyboardManager 3rd party library for handling the keyboard without any effort at all. I believe Digits has a manager for keyboard too, and that conflicts with my IQKeyboardManager.
