It is the third ranked match I won and the mastery xp is not being added to the mastery progress. I am 975/1000 xp for the next level. I am not sure how long this has been happen. Three matches ago I looked at my mastery progress and saw I was 25 xp away to the next level. I played and won one ranked match, and the progress kept the same. I thought maybe I was mistaken about the amount, checked again 975/1000 xp. I played one more, won the match and nothing. Then, I closed the game and opened again. Checked the progress, 975/1000xp. Played one more, won the match, nothing happened.
