Not just the app.... Not the first time that Instacart had done this either... I placed 2 different orders from 2 different stores within 30 minutes of each other. The first order is allowed through. The second is not, and my account is logged out of the app and frozen. I tried verifying two different ways as I was instructed without satisfaction. I have to go in a browser to Instacart to find a number to call them. The representative says he and everyone else is only tier 1 and cannot help me.
