So I was trying to redeem the waypoint codes for getting the achievements in Halo Spartan Assault, and every time I type in the codes for the Recruit and Prodigy achievements, it rejects them and tells me I still need to unlock them. To clarify I unlocked them on the Xbox One version of SA. Any fix or something I can do? Also a little off topic but when I try to search for people to play coop on SA, I can never get anyone or even connect with my friend who has SA. I live in an ASU dorm with strict NAT and can’t do much short of buying my own router which cannot be done, but even when I was at home with open NAT it didn’t work then. Thanks for any help.
TL;DR waypoint codes for SA achievements received on Xbox one does not work, and neither does coop search on strict NAT
