user profile mapping - export / import settings
We have huge customization of mapped user data in User Properties in UPS and of course full sync with AD bidirectional. We will welcome some kind of dump of the settings with possibility of scripting (at least export / import settings to UPS)
Please re-activate UPS mapping in SPO. Not being able to consume Azure AD user attributes (other than default) is horrible. CSOM solutions while possible, are in no way practical.
If we use sync tool to get an attribute into Azure AD, it should be able to be consumed in SPO via SPO mapping!
