[REPOST] Weapon Mastery not tracking

PLEASE COMMENT AND LIKE SO PEOPLE CAN SEE THIS EASIER. EVEN IF YOU DONT KNOW A SOLUTION, PLEASE HELP ME FIND SOME WHO DOES!

When I first installed the game, everything worked normal. I’m using the M2010 ESR. I got it up to level 12-15 before the problem started happening. My Weapon Mastery stopping tracking towards my weapon, and I couldn’t level it up. However, about every 6-10 games I played, the bug would stop and I would be able to progress the mastery again, but that would only last for 1 match, maybe 2 if I was lucky before it stopped tracking again. To make matters worse, each match I join is usually about to end, so I have no time to play. That includes the matches where the bug stops happening. Most of the time, I’ll finally get it to start tracking again, but the match I join ends almost immediately, leaving me with little to no xp even gained. I am playing on basic All-out warfare, conquest, and breakthrough. There are no bots in my lobbies, and it is a core game mode. I have tried restarting my game several times, didn’t work. I’m not a genius when it comes to troubleshooting, so I don’t really know what else to do. I’m very upset about this because I’ve been trying to unlock a better optic for the M2010, since I don’t like the 6.00x, but now it’s pretty much impossible. I haven’t found anyone else talking about it, except a few people (4 or 5) I am on Xbox, but I heard this is happening across platforms. Please help if you have any solution or advice.
