Prestage to Prestage and enrollment - iPads

This happens to me sometimes if I turn the iPad on (if it's brand new) then put them on their respective pre-stage and I usually have to do a wipe command for that correct pre-stage to kick in.

I had better luck on switching the pre-stage first before turning on the iPad.

I usually just group my iPads together and add them to a PreStage Enrollment. I would plug them into a iPad Cart with syncing capability, then use Apple Configurator to pull the serial numbers. Then i would mass wipe all 30 then add them to the Prestage. At that point i add a Wifi Configuration through Apple Configurator 2 and they all enroll into the right spot.

That issue you are having is the exact reason i don't have a global configuration. Devices bought through Apple and using Device Enrollment Portal usually has my devices ready to search by the time my iPads arrive.

The problem is, I do not physically have these devices most of the time. They are shipped out to one of our many, many, sites and the tech for that site is doing the enrolling. I snatch up the PO and put them in prestages before the tech gets them, but I always inevitably get an email that something is not enrolling properly out of the bunch.
It's not a global configuration profile, it's just a setting within the prestage to require credentials, and then I move them to a prestage that does not require credentials. I was able to get two of the affected ipads to my office, and I let them sit overnight. I wiped them when I arrived in the morning and re-enrolled them - but the problem persists. It just doesn't see the setting, and continues asking for credentials to set up.

It's indicating that it is in the correct prestage at the moment, but when I go to that prestage and the one it was moved from it is not in either. This is so weird.
