I have got the Bungie mobile app and it says there are no accounts link to Bungie.net yet I have linked my Xbox, PSN, google, and Facebook accounts yet there is still nothing. Also when I click on legend on the mobile app it says I have not played Destiny, but I have played alpha (watch the video for proof) so if anyone can please help. Thank You.
Everyone's Alpha stats were wiped clean & it's a known bug. your account is perfectly fine. There's a fix coming out shortly that will correct this.
