Unifi updates including this one are virtually always accompanied by firmware updates for the APs. Upon AP update your Wifi may go down for a few minutes while the APs say “provisioning”.

Insights > “Neighboring Access Points”

“Neighboring access points” shows you any other AP (including hidden SSID listed by BSSID) and it’s fascinating to see how much better (more sensitive, longer range) the AP is than your mobile device. You may see distant SSIDs that you’ve never seen from a mobile or laptop in the same office.
