Xbox Live authentication URL

Hey guys, I am making an iOS app called Loadouts for Destiny ( http://loadoutsapp.com ). Can you please settle on the URL used on the site to authenticate with Xbox Live? Two weeks ago it was https://www.bungie.net/en/User/SignIn/Wlid?bru=%252f A week ago it changed to https://www.bungie.net/en/User/SignIn/Xuid?bru=%252f I have rejected the binary and resubmitted it to the App Store. Two days ago it changed back to https://www.bungie.net/en/User/SignIn/Wlid?bru=%252f 1.0 was approved and it turned out XBL login isn't working. I have changed the URL back and re-submitted, asking for an expedited review, and... Today it changed AGAIN back to https://www.bungie.net/en/User/SignIn/Xuid?bru=%252f All this caused my app be unoperable for XBL as every time I change the authentication URL and re-submit it to the App Store, the latter changes on the site and it stops working again. :( Could you please settle on one URL without changing it every few days? :)
