On my InstantOn deployment I have WPA3 turned on for some SSIDs. I recent migrated to the latest MacOS (Catalina) and had problems getting there. My installs would end in the black screen of death (similar to the windows blue screen). I've tracked it down to WPA3. The instant I try to join a WPA3 capable SSID it dies. If I change that SSID to just WPA2, it dies. Anyone else have problems with WPA3? Some of my SSIDs supporting home automation it seems I had problems with WPA3. So maybe it's just half baked.
We recently identified an issue where certain clients had trouble connecting to SSIDs with WPA3 enabled. Changing the SSID to WPA2 gets rid of the connectivity issue. This issue will be fixed in an upcoming software version.
