Hello! We are excited to announce Steam Families is now available for all users. Steam Families is a collection of new and existing family-related features. It replaces both Steam Family Sharing and Steam Family View, giving you a single location to manage which games your family can access and when they can play. Create a Steam Family To get started, you can create a Steam Family and then invite up to 5 family members.
I cannot invite my gf to the Families, while we could do Library share before just fine.
Just sign in with her account on your pc, invite her and then you can sign out. I had the same problem.
Why not?
Replied in other posts, it likely is because you have to be in the same country/steam store region or something…
A lot of work but: have her VPN into your residential network and send her traffic through your ISP for a while.
5head tactics haha.
