Beacons assigned to a subordinate Manager will still be visible in your Web Panel beacons view, but cannot be edited by you.
When you check your beacons in the Web Panel, some may not be editable i.e. The information under GENERAL is grey. You cannot see ACTIONS and SECURITY information.
In the screenshot below, you'll see that the first beacon listed has been assigned to another Manager.
To edit these beacons, you'll need to either sign-in to the Web Panel as the subordinate manager, or re-assign them back to yourself.
