Why can't I change the difficulty in season mode in Madden Mobile?

I like this game. I really do. But there are several VERY annoying things about it. First, it's extremely hard to get coins, so for a while, your team will suck. Also, you can't purchase coins, so that just makes things worse. Secondly, I would like to see the option to play players at any position, like in Madden 16. Finally, (and most importantly) I NEED to see a change made to season mode. More specifically, the difficulty. Once you get to season 4, it becomes incredibly difficult to win more than a few games a season. I have an 80 overall team, yet when playing 73 overall opponents, I can't run for more than 2 yards per play, and EVERY pass, is either dropped, or intercepted. So, if I don't see ONE of these things fixed by the next major update, I am sad to say I will no longer be playing Madden Mobile.
