Reproducing this bug has led to the uncovering of another bug which has interrupted progress at times. When adding a 2nd account, after entering country and phone number data (and confirming), the app hangs with a spinning wheel before the number confirmation dialog is displayed. The log on the console states:

UTC qml: sourcePage must be added to the view to add new page
