Of course, a CSS provider can also remove Merchant Center from its CSS. To do this, he sends a request to Google Shopping Europe via the CSS Support Portal and requests a Merchant Center switch. Google Shopping Europe then sends a CSS switch request to the Merchant Center.
Once this request is accepted in the Merchant Center, the switch back to GSE is complete. If the Merchant Center admin refuses to accept the request, the CSS provider can request the deletion of this Merchant Center.
