Hello, I recently invited a friend to join my Steam family. When he accepted the invitation, I was able to access his games, and play them normally, but he was unable to access mine.
If anyone can help me resolve the problem, I would be grateful.
Thanks.

Dear user, I recommend that you first approve the curator in Steam Family (Adult), here you can choose which games (child) will see, you will also manage many functions of his account, of course you will be able to get access to his library in this case

Ok, thanks
