Great game But Need Help – My Little Pony Pocket Ponies Review

I’m on Cadence’s 5th challenge, and no matter how many times I complete the fourth one it never unlocks. There are no other challenges available and it says I must complete the previous one before I complete this one. I’ve tried closing the app and getting back in but nothing. I think this game is super fun, and I’ve already spent hours on it. I just really am stuck on this part and need some assistance, and there’s no support. Please help fix this!
