[2020] [Connectivity/Multiplayer]Missing MMR

A couple days ago I won a ranked match 4-1 and I didn't receive any MMR for winning the game, so I restarted the game and xbox to try and resolve the situation, but that didn't work. So then I recorded the last 5 minutes to see if I could see anything strange. It turns out the game was trying to synchronise data and I left without realising and I've tried contacting customer support and they haven't helped. So Im posting this to try and get my MMR back if needed I can provide the video to show I won the game

my GT is jack6487 on xbox
