I am not sure if Joesthedj got his issue resolved but now i am having the same troubles he was having.

At first I thought it was just cause it was the post season and the x2 would come back once league started. But i havent even watched a vid today in hope that the x2 training bonus would come back but still nothing for me

Device- Apple Iphone6, ios
I can watch vids for boosters.. just not for x2 training.
