Just installed the Android app and entered my details as requested.
Regarding date of birth, I’m 60 plus (probably not your target audience but still…) so the pop-up to choose the date only offers the current date and a step-back-by-month arrow. Can you imagine how long it took to get back to my birth month in the 1950s ?!
There didn’t seem to be a ‘manual’ way to type the date in so you might want to look at that input in future versions of the app.
Anyway I’m now in the queue and eager to try the card.
Hope this a useful feedback.
