Question regarding managed iOS devices. Our iOS security policies state that the user must change their PIN code every 90 days. When you setup a PIN code initially the numerical PIN keypad pops up. However, after 90 days when they are forced to change their PIN, a full QWERTY keyboard pops up asking the user to change their PIN and not just a numerical keypad. To add, if a user manually changes the PIN code before the 90 day period by going to "Settings > Face ID & Passcode" the numerical PIN code does come up.  Also, I can confirm that our iOS policy shows Password type as Numeric (and NOT Alphanumeric).

The crux is that the users are changing their PINs from a numerical PIN to a alphanumeric PIN (because they see a full QWERTY keyboard) and they get this confused with their network password. I've put in a ticket with MS Support on this and was advised that there's nothing they can do about this.  As I understand it, in essence this is an Apple issue where they'd need to open up their API's.

Is that right? Is there anyway to change this full QWERTY keyboard layout to just a numerical PIN keyboard when the security policy dictates this? It's an issue I'd like to solve in our environment as we constantly get HelpDesk tickets regarding this.
