If you click on Integrations in your AppScenic Account, and under STATUS you have 

Re-Authenticate, then you need to re-authenticate your store. 



Until you do this, your products won't be in sync, such as Price and Stock. In other words, the products on AppScenic won't be in sync with your store. 



You will also get an email and a pop-up on your Dashboard reminding you to take this action. 



This is what Re-Authenticate status means.
