No, I didn’t need to download a photo either. Admittedly, it’s a few years ago so I don’t know if it’s changed.
Perhaps call into your surgery and seek their advice on how to download the app.
If memory serves me right, when I called in to the surgery they printed off a password they said I needed to input, but I seem to think that I didn’t actually need to use it, my NHS number and DOB details were sufficient.
That all rings a bell. To see the surgery site, with prescription ordering and to book nurse appointments I got a password, which I still need, although it is stored on my laptop. I took my passport in to get that, I think.
The national NHS app had less security for some reason, or maybe it was linked to the surgery one, although they each get different information, strangely. The surgery one has (eg) blood test results if they are ordered by a GP but not a consultant, and the NHS one doesn't seem to show test results at all, so I ask when I get a follow-up appointment. It means I have to keep my own records to see things in the same place, which is irritating.
