for some reason the option to make custom challenges is not on my challenges page. please help me with this i have tried 2 different web browsers. and the waypoint on the 360 says nothing about custom challenges as well. And i had my friend make me some challenges on his computer and i dont get the progress for completing them either. someone please help with this its not cool. =(

Are you positive you are signed in with the same e-mail that is associated with your gamertag???

Do you have an iPad/iPhone/iPod Touch? The Waypoint app is very user friendly…
