Hello,
I set up a steam family so my partner, my father/his FIL, and I could share games. When my partner tried to accept my invitation he got the error message "You are ineligible to join this Steam Family at this time, as your Steam activity doesn't indicate that you are in the same household as other members of this family." He only recently got back into playing PC games, so he and I haven't been friends on steam for very long. He is also currently in a different country.
Is there any way to fix this error and let him join my family?

Thanks
