I have users in the contribute group and they are seeing Region: null(4) in the library view. The site collection admin can see a view with Region: SW(4) which is group by region (region is a managed metadata single value and not multiple value).
The end user can edit properties and able to see managed metadata (meaning available for tagging is working) and select a value and save the document. Even all items view does not show the MMS values for Region column for contribute users. What am I missing?
