Ok, long story coming up.  Please bear with me...   Our MDM certificate expired.  The boss had it on his calendar for renewal, but last year renewed it a couple weeks early, and forgot to change the calendar entry, so it expired...   So we created a new one, and manually re-enrolled all of our 200 iPads into Meraki -- we made sure the Meraki Systems Manager app was up-to-date, scanned in the bar-code to install the Meraki Profile, and everything seemed to go well...   Now, suddenly, two weeks later, our apps won't update...  I needed to update one of our apps, and if I push that update to any Meraki-controlled device, BOTH our apps disappear!!!  They appear for a very brief second, and then they simply disappear! I have googled this issue, and the only thing I can find is that the profile restrictions are set wrong.  So I created a profile with NO restrictions, installed Meraki onto a single iPad with that profile, and STILL the apps will not install.   So I'm thinking maybe there's suddenly an issue with the certificates for the apps somehow?  The cert for one of the apps expires in a month anyway, so I figured I'd go ahead and revoke all my certs and re-do everything from scratch for both apps.   But then I noticed - NONE of our devices are registered in the "devices" section of our Apple Enterprise account manager?  Did we need to do that?  Or is that only for testing?  Because we *do* have several test devices registered in there -- devices that we *do not* use Meraki on, but are only used for debugging/testing before we distribute the apps...   So, it all boils down to this: Do I need to register all our devices on our Apple Enterprise account in order for Meraki to work?  Or is there something else I must do, like using Apple Configurator?  Will Meraki work without Apple Configurator?   I'm just very confused as to why nothing is working anymore -- and all of the sudden, even though we've changed nothing.  If anyone has any ideas, I'm open to suggestions.   Thanks, ...
