Has anyone experienced this issue?
I’ve recently returned to the MP on Xbox Series X. I lost so many hours of grind in the past few days. I play completely normal matches with no hackers boosting or bot lobbies, but every single time I exit the Multiplayer mode (by going to the main menu) I lose that session progress entirely. During normal gameplay I can basically play and progress completely fine too. I never experienced anything similar in any old CoD game…
It’s just so frustrating and honestly it makes me want to quit playing completely.
Thanks in advance.
