Hi Everyone,
The latest information I have is that the Shopify legacy feed is shared from a Business Manager inside Facebook Ads Manager that is owned by Shopify. So FB helpdesk has said someone needs to go into the Shopify BM account and unshare the feeds to stop them populating our accounts.
I have a ticket open, so will let you know if I get it resolved. But it seems like the action is on Shopify to unshare the apps into our accounts to remove the dead feeds.
FB wont edit anything inside an account, not sure why it’s built so you can’t delete a feed in your own catalog manager, but short answer is the feeds originate from an app owned by a shopify business manager, and this is pushing these out of date feeds into our catalogs.
