Three weeks after receiving the card, I finally received the physical PIN, something that I'd retrieved via the online portal weeks ago. Why do they bother sending this at all?
Besides the Android app generally looking like it's stuck in the noughties, and Google Pay not working on my phone, and Apple Pay not working on my missus' phone, and a couple of random declines, and a few oddities like transactions from 10 days ago still showing up as pending, and the web interface constantly logging me out seemingly arbitrarily, and being forced to use the app or the browser interface for accessing certain things, I think everything else is going quite well.
