It's been working since a day or so after launch. Are you sure you're doing it right? You need to log into Facebook/Twitter on the Share Campaign website, with the child you have chosen, and click the "Claim" button. Then you add your in-game information (User Code as well as current Crystals/etc.) and hit submit. Then the child is sent to your mailbox.Is there any news on linking Twitter to DC for the free 5* still working or am I just doing it wrong? Wanted to rr a bit trying for Maat or an attacker
