Hi @Hooch,

If you set ''lock to AP'' for your devices, when these devices try to switch to another AP, it will be blocked. You can go to ''Insight > Past connection'' to check the lock to AP record for each client. Then in the dashboard of the controller, it shows blocked by access control.

And the R&D department plans to optimize Blocked by ACL Log in the subsequent firmware released to refine exactly which function Block's name is displayed by, so please keep an eye on the official website and this thread.
