Hi there!
TBH, I haven’t been on Waypoint for quite some time, before this new upgrade. I’ve gone to my career stats page and found that all progress on previous Halo games has disappeared, including Waypoint achievements!
Is it a case of jumping onto my Xbox, loading the app and my info will sync again? I am a silver member and had also changed my gamertag a few months ago from PMS Legend to pawncrackers.
Could anyone shed a light?
Thanks 
L
