叫他把账号给你，然后在你电脑上多登录几次，然后在家庭组客服那里反馈，一般来说几天就好了

Hello! Here is my question: After the release of the Steam Family Sharing beta, my brother (who is related to me by blood and is also my Steam friend, ID: ╳╳╳╳╳╳╳) wants to add me to his Family Sharing group. However, no matter what I do, I always receive the red error message on the joining page saying "You are not eligible to join this Family Sharing group. There is no evidence to suggest that you and the members of this Family Sharing group belong to the same household." But, without a doubt, all the members of the aforementioned Family Sharing group are my direct or extended family. I don't understand why I am unable to join my own brother's Steam Family Sharing group. I think this is ridiculous. Do you have any solutions? I hope I can join the Family Sharing group as soon as possible. Thank you!
