Ever since Destiny launched no one has been able to join my fireteam unless I sent an invite to the person. The would get the error "Unable to join fireteam. Please try again later" error. I thought the source of my problems was my terrible local ISP that i finally ditched today for Comcast. After everything has been set up, still noone is able to join without an invite. I have tried to change the Join In setting via this article: https://www.bungie.net/en/Help/Article/12186 , but that still doesnt work. Does anyone know of another solution or know of a reason why this is? Possibly a privacy setting?
