I was very excited by this, but I found that some of my dumber IoT devices would refuse to connect to the network if it used PPSK. If I connect them to a separate SSID I use for IoT devices with a basic WPA2 PSK, they work totally fine, but I didn't dig too much so it could also be user error
Ah ok, strange that the feature is only becoming mainstream now (as in added by Unifi, and I never heard of it before). It's very good to hear actually because most of the devices I want to have on separate VLANs are quite dumb (IoT home automation stuff in particular) and they won't have WPA3 (and often even only have 2.4Ghz).
