Manager known issues

CRITICAL:

Reference Number	Related Article	Found in Version	Issue Description
1270723		9.2	Issue: In a Manager Disaster Recovery (MDR) pair, when you double-click a policy from the Inspection Options Policies page of the standby Manager, you are logged out of the Manager. Double-clicking a policy in the standby Manager only allows view access because objects in the standby Manager are synced from the active Manager. Workaround: You can view and optionally modify a policy using an active Manager's Inspection Options Policies page.
