verify other user 'hangs'

### Steps to reproduce

2. Go to settings
3. Go to profile

### Outcome

#### What did you expect?
That I get the images for verification. That I can select with both accounts that they match and that I get 'Verified profile'

No file, test, or entry point is identified. First reproduce the user-verification flow on a Google Pixel 8, then trace the verification screen from the existing DM and settings/profile steps; done means verification images load, matching can be confirmed on both accounts, the app does not hang, and the profile becomes verified.
