Why can’t I get coins without purchasing the treasure trove ? – Toy Story Drop! Review

I was really enjoying this game but all of a sudden I stopped getting coins awarded to me and the only way to get them is by purchasing the Treasure Trove that is full. It is full because I played so much and earned them but once it was filled the only way to claim them is to purchase them. Please bring back the free coins !
