Not enough coins

With the update, there's more to do, but the coin acquisition rate is poor. It's my first time playing a game where coins, which are usually abundant enough to feel like you have too many, are actually insufficient. The game balance is bad. I'm at my limit with watching malicious ads that force long screen transitions and then crash the app when I return. Since they won't accumulate anyway, I'll watch the minimum required ads, play casually, and if the stress still outweighs the fun, I'll quit. Don't they realize that long ads are a bad move that drives players away?
