I don't think its really anything to do with the AP firmware.. So I don't think they will be able to fix it.. From what a few were saying has to do with the different auth that wpa3 uses..
Not sure - have not dug that deep into yet. I was really hoping to just have guest be limited to wpa3.. But I will live with this compromise.. Just thought give you a heads up if you were doing the same thing.. And you had friends come over - and you get hey this qr code thing isn't working ;)
