On the Integrations section of your AppScenic Account under STATUS, you will see either CONNECT or DISCONNECT.

CONNECT - if your Store is Connected - product updates such as Price and Stock which are made on your integrated store are reflected in AppScenic. In other words, the products are kept in sync with your integrated store. 

DISCONNECT - if you click on this button it means that you want to disconnect your online store; this will mean your products will not be updated anymore in AppScenic if they change in your store. Remember to connect it if you want it up and running on AppScenic once again.

This is what CONNECT and DISCONNECT mean.
