Hi,    We are currently experiencing an issue with an Expired DEP certificate and we are unable to re-enrol around 250 without factory resetting every IOS Device. We have tried re-enrolling using m.meraki.com however receive an error due to the expired DEP certificate already being installed, this appears to leave us with no other option than factory resetting all the devices to get them to re-enrol with DEP.    Really looking for any way to re-enrol these devices without the need to factory reset every handset if possible,  this is going to be very time consuming and will cause allot of upset with our users.  Failing this then does anyone have any suggestions on how we can make this process easier.    Note: the previous certificate was replaced around 7 months ago and we don't have a copy of this, we contacted apple to check if this can be recovered however they have advised it cannot.    Thanks    ...
