Resolved: Known Issue with importing Windows Autopilot devices using Order ID in CSV

When Autopilot registrations were done via the MS Store for Business the groups were easy to add (at the time of import) now seemingly the tags need to be added in the CSV file, which i have working but seriously - another manual step in a process that is all about automation.  And what happens if you tag it wrong?  I see no way of changing the group tag once it's been set.  Considering may of us are using this to create dynamic groups it seems sensible that this would be something you can change.  I mirror the comment from Jan Gutjahr the communications on changes for these systems need to be clearer.  I raised a case with MS Support as i was unable to register a device using autopilot,(still unresolved) and neither of the two support tech i have spoken to wee even aware you could register devices through MS Store for business.  I'm still confused about whether i should even be using that anymore or not and if so what for?
