You cant add items to your cart

This app is great when it works but right now you do all your shopping and you click to add items to your cart and it will say that it added it to your cart and it will show the number of items you have in your cart. Then when you go to check out its completely empty! So much wasted time adding things to my cart to buy only to find out its empty!
