It started well. I have an Android phone!
Not the right kind of Android phones though, so had to borrow another one...
This means I will have to send my passport to the Home Office, which is never a fun thing to do (thankfully, as many EU citizens I have a second form of ID). 🙃🙃
All years for which I have P60s – but was earning next to nothing (teaching 10-15 hours a year during PhD). So… additional evidence needed for full settled status.
Anyway - this didn't happen with code sent by email, logging on a phone 🙃🙃🙃, so eventually was able to log back in and upload proofs of my water usage of 6 years ago.
