Frustrating. Issues are several: 1) App reports my store is closed when it is actually open. 2) After adding products to shopping cart, I cannot access the cart and hence cannot make a nearly $2,000 purchase. Lost sales are not healthy. 3) Sometimes simply trying to open the app is a failure. It tries to tell me I don't have an internet connection which is just a bogus error. The problem is the app, not my internet connection.
