Eufy Security - Family (extra) phone not showing in "geolocated detection option" in security profile

Hi. I ve bought a pan an tilt cam and regitered it on my eufy security tab on my iphone. I was very interested with the geolocating profile to activate / desactivate notification, as as so i was willing to add my wife iphone to the activated units.
I ve followed what i thought was required. Send her a invitation using the app with no admin rights. Create her an account, install her the app. I now see her in family and invitee, i see that she sees the camera in her profile, but her phone is still not appearing in the possible activated units of the geolocating secutity profile.

Can anyone tell me what i have miss ? :s
