Seems all new students imported into jamf from ASM come in with the default Passcode Requirement (found in Users Inventory > Rosters) of "Complex" even if the Password Setting in ASM was 4-Digit.
So, when student sign in, they are presented with a complex keyboard screen to sign in with a 4-Digit passcode.
There doesn't appear to be anyway of changing an entire class of students in jamf from complex to 4-digit either. Meaning you have to change one student at a time.
Doing this for several hundred students takes a LONG time…
