Network Manager Access Point WPS Pin Disable

we are opening an Access Point with network manager (on a RPI4 with Raspbian) and everything is working fine except that when connecting from Windows 10 we are asked for a pin first (probably wps pin) instead of getting shown directly the passphrase field to enter. This is not observed on Mac and Linux. Our wifi-ap configuration: sudo nmcli c add con-name wifi-ap type wifi ssid test ifname wlan0 save yes autoconnect yes 802-11-wireless.mode ap 802-11-wireless.band bg ipv4.method shared wifi-sec.key-mgmt wpa-psk wifi-sec.psk "test1234" We already tried multiple configurations from the provided page: https://developer.gnome.org/NetworkManager/stable/settings-802-11-wireless-security.html like: - wps-method 1 - proto rsn - pairwise ccmp But nothing really helped. Would be fantastic to get your support here. Thanks
