On opening the org chart TeamOrgChart will build an index and depending on the size of the organization, this may take a few minutes.
TeamOrgChart will calculate the top of the organization by walking up the manager hierarchy starting from current user (you) and save that person as the head of the chart. If the manager data within your Entra ID is correctly set, you should see an organization chart. The chart starting position can be changed at a later date as required.
The chart is fully functional at this stage, you should be able to search, navigate and bring up the information window for people within the organization.
