WPS Accept not available on Virtual AP.

I have selected ‘virtual push button only’ in WPS Mode on a virtual AP interface. The security profile is WPA2 PSK. The WPS Accept button does not appear in Winbox for the virtual wireless interface. How do I get WPS to function on the virtual wireless interface.

Routerboard is RB751G-2HnD
ROSv 6.36.2

I can get WPS to function on the master wireless interface, but not on the vAP. I only want WPS on the vAP interface.

Sincerely,
Daniel
