Thanks @sam, it’s definitely much more usable now.
I did notice a small issue still.. if you have external login buttons enabled, the scroll jumps a little when moving from the username to the password field, and the cursor on the password field is not visible.
This happens if you tap on the password field after entering your username, or if you use the down caret button in the keyboard toolbar to move to the next field.
If you tap the password field again after it gains focus, the cursor appears.
