What is the difference between the Google Merchant Center and the Google Merchant Center MCA connector?

The Google Merchant Center connector is designed for businesses managing a single Merchant Center account, allowing them to upload and optimize product feeds, monitor feed health, and manage product listings for their eCommerce store.

The Google Merchant Center MCA (Multi-Client Account) connector, on the other hand, is tailored for agencies, aggregators, or businesses that oversee multiple Merchant Center accounts under a single parent account.
