my gamer score went from 507000 to 370000. Will this be fixed?

If the missing score is from Xbox One games, it's a glitch that will fix itself on its own, usually after a few days.

Have you been banned from any microsoft games?

Hi there,

If you did not receive a Gamerscore correction, which would show
here, it most likely is a glitch that will correct itself in a few days. A few users have experienced this glitch so you aren't alone.

My gamer score has gone to zero from 102750 any idea when fix is available

I tried re-downloading, my gamer score went from 22k to 5 in a matter of seconds as i woke up having left my account up, i tried to play a game and it said i'd previously played it from another console, which i hadn't, then my MS points went from 320 to
510, its defiantly a server thing as i know alot of others are experiencing it but how to fix it..i don't know.
