Retrieving Data Error

so this began a week ago today, I’ve been trying new things since then and still nothing has worked.
Firsf, I thought hey maybe the servers were down and waited a day, then 2, then 3.
(yes is continued to check in the error, resetting my internet probably more times then you could count on your hands, uninstalling and reinstalling the game and even factory resetting my xbox… Nothing works! I’m completely lost and have no idea what to do. Tried coming into contact with 343 but couldn’t find a way. Anyone else experience this and was finally able to make it work again?

yup, I’m getting this issue as well.
past 5 days. besides matchmaking, can’t do anything at all in Halo 5. I’m beyond frustrated by this.
