I just updated to iOS 13.1.2 from iOS 12.4.1. In so doing, I noticed right away that I can no longer enter the amount of a mobile deposit using the keyboard preented by the Wells FArgo app, which has not been updated yet for iOS 13. This indicates possibly something in VoiceOver has changed. Note that this worked for me three weeks ago when I made a previous deposit into the app.
What you get when doing a deposit is a button which asksyou to enter the amount. Double tapping this button brings up a numeric keypad. But if you are using touch typing (which I do), you cannot simply touch the button corresponding to the number. You have to double tap. But if you do that, you get two digits entered instad of one.
