Prime 4 wifi problems 2.2.2 WPA standard

Hi there! After updating to version 2.2.2, I had unexpected wifi problems with my Prime 4. Sometimes there is only a short connection possible (1 min), sometimes the wifi login failed (password correct). Changing my wifi setup from wpa3 back to wpa2 solved the problem until now. The router does wpa3 and wpa2 at the same time, but the Prime 4 seems to have problems with choosing the right standard. Are there any known issues regarding wpa2 and wpa3? Or is the Prime 4 only capable of wpa2?
