Can't get through "User Configuration" on new PinePhone

[rocket2nfinity]

I feel silly, but have now spent many hours trying to set up my new PinePhone.
Have watched many videos and read many posts, but none mentions this issue.
After the KDE symbol comes up, everyone talks about a PIN screen, but that's not what I get.
I'm getting something called 'User Configuration', where it asks for Full Name, Username, and Password.
After (I think) entering those (it's very awkward because it just shows the keyboard - I'm hitting <CR> and
      then have to push the Power button to see the entries!) and using '123456' as the Password, nothing happens.
I'm sure there is a simple explanation for this - can someone please tell me what I'm doing wrong?
Thanks in advance, everyone.

I've had this before. Try pressing and holding the top of the configuration window and drag it until you see the next box. You could also flip to landscape mode. Makes it easier to get to.
