After upgrading to AA 8.8 from AA 8.7, in the web console AD health topology never loads up.
On web console for health, when you go to the Active Directory Topology and loading forest data all it does is keep spinning. Tried it with different browser like Edge and Chrome but still the same issue.
As such we have created a defect to have this corrected in a future version of Active Administrator. The defect for this issue is 539199.
