Nuki Smart Lock Pro (3.0 and 4.0).
The smart lock currently works in WPA2/3 environments, but is not compatible with WPA3-only networks. As a consequence, the lock is incompatible with WiFi 6E (6 GHz) which mandates WPA3 and PMF.
The smart lock should be able to connect to WPA3-only networks.
Anyone with a WiFi 6E compatible phone (e.g. iPhone 15) and a compatible router / access point who wants to benefit from WiFi 6E has to add an additional SSID for WPA2/3 just for the smart lock. This compromises network security and add beacon overhead which takes up airtime (slowing the network down for everyone).
