Hi Sean,
We are mainly an Apple household in the UK(i know, i know!) and everything seems to be connecting just fine as far as i'm aware!
Most of our devices are working on the 5G AC band, but we do have an older Windows laptop thats 2.4 only and so far, all ok.
One thing i did notice was how much quicker and smoother throughput is on these AP's and also, none of our devices (mainly iphones) are falling back to mobile internet when they sleep.
So, all in all, they are fantastic and a huge step up on my previous 'enterprise' APs, and so much simpler to install.
Once i plugged them in and found their IP, i had them BOTH set up in about 15 minutes, rather than the 2/3 hours before of setting up, rebooting AP's reinstalling controllers etc etc etc!
