How do I get past "try again" when trying to edit settings after installing Square Connector? I have deleted cache, logged out and in and I am still receiving the error?

I disconnected the old Square app and then added the new Square Connector by Quickbooks. When I goto Sync transactions I receive the message "Try Again later" I have disconnected from Square and tried logging out of both square and Quickbooks, deleted cache and nothing seems to help. Any advice is appreciated!
