I have noticed that the progression my players get in 1 particular season is only like 20 percent for the first friendly match, while on other accounts it's always 50+ for the first game. Even now with the Extreme progression Event going on, I did a friendly game and it still only went up like 18 percent. All the players the have gone up are younger than 24 so it's not an age problem. I am however far into the season and noticed that the first couple of weeks the progression rate was normal, but the last 10 or so days it's been very low.
Any reason for this? Is it bugged? Or is it because the season is almost coming to an end?
Most likely a bug
As the season goes progress, players progression begin to decrease. No bug!
