The shoppers vary in quality, some are very good. But the app makes communicating with them very difficult. The chat does not reliably update, nor does it reliably provide you a push notification for a message. You need to check it often, and even then you may get the error screen and need to either refresh or restart the app. Waiting for a notification your groceries were delivered? You won't get one. Not every shopper rings my doorbell, so food sits out. Fix this please.
