I am developing a tool that checks whether a TM is linked to other organizations.
This used to work well with GroupShare 2020 SR1 CU4 and the GS Developer Kit that was used at that time.
With the latest 15.1.12.3 version of the developer kit and our GS 2020 CU11 test server the following properties throw and object reference error, e.g.:
objTM.ParentOrganizationId
objTM.LinkedOrganizationIds
All other properties such as Name, ID, ResourceType still work fine.
