please fix – InstantCatch for Instagram Review

This app is so great and easy to use. But lately it has been having a problem. Not sure if it is just me or it is happening with others. When i go to watch an ad in order to get coins, it tells me to wait 15 minutes which im okay with. But even after 15 minutes passes, it still tells me to wait. I dont know whats wrong. Help
