Instacart tells me I'm an excellent Shopper, yet their APP issues make the customers unhappy. Messages and pictures do not get to customers in a timely manner. Delivery timing is never adhered to for the customers requested or given delivery time. And NOW, I've been put in an awkward position "to knock or not to knock". The delivery instructions are confusing! ALL of this reflects on ME, not YOU because I get rated based on those issues. It is not right!! Fix this!!
