When attempting to add additional groups via group inclusion, the UI fails to save the policy. The UI allows the selection of the groups and for the list to be saved, but when clicking "Save" to actually apply the policy it fails to save the policy.
Endpoint Detection & Response (SEDR) 4.1 or earlier.
The database field within SEDR that saves the group path is limited to 128 characters.
A fix for this issue was included in the SEDR 4.2 release. Please update at your earliest convenience.
