Since the release of Google My Business, Google My Business limits on the maximum number of listings/locations an account has changed. Go to Maximum number of listings per account for clarification.
If you are posting to Google My Business Listing that has more than 100 locations (franchise) you may receive the following bounce message "This location belongs to a chain. The Local Post API is disabled for this location" as Google My Business has added limitations depending on when the listings were created.
You can manage the limit of the number of Google My Business Listing for your account by requesting bulk verification.
