UK Immigration: ID Check

The app is very slow to load, and it often stops working half way when you are trying to load information. Very frustrating.

I had a name change and got a new passport after my eVisa had been approved on the old one. The app worked fine to add my old passport. I should be able to add the new identity document in a similar way: going through the flow brings me back to this app. But although it seemingly scans the new chip fine and gathers all my new info correctly, when I submit to the server the new passport number never appears in their system. My options are (1) a new biometrics appointment at my expense, which I find offensive, or (2) post documents to an office in Liverpool after arriving in the UK. Meanwhile I had to get a standard ETA on the new passport, even though I shouldn’t require one, because the airline could refuse me a boarding pass if the new document isn’t connected to a valid visa. Infuriating. If the system only worked, I could avoid so much hassle.
