I have set my new name everywhere I can in the AppleID settings but the old name is still showing up in this place, and maybe in other places which I haven’t seen yet. But how can I get my chosen name to show up here?
(for clarity, this is the profile picture selection on iPadOS)
Solution: The solution for me was that I had to change my name in the contacts.

Currently, there are no way to change it. I know the pain, I have a almost two decade old cringeworthy name.
Thank god I’m not the only one >_>
