players attributes not increasing??

So I started playing a couple of months ago and the game worked fine on my Android phone until the new update dropped and now after any match or practice session, my players gain some growth points (the training cones were better) and show some attributes increasing but when I check out the player info, there is no increase in the players attributes. Some of my players are the same skill since the start of the season without any increase. Please let me know what I'm doing wrong. Any help would be appreciated. Thanks.
