I am having a similar problem with my Shopify. I am having issues setting up the catalogue because it keeps saying
Enable Facebook Shop to make it easier for customers to browse and buy your products.
Your Facebook Shop is in review. You can enable it once it’s approved.
I am not sure where to reach out to have this issue looked at.
We are having the same issue. Our shopify website went offline, so our Facebok Store got disconnected. We reconnected it two weeks agothen it read your store is in review. This remained for a week and a half and nothing happned. We disconnected this past week and reconnected and its in review again and three days have passed and it still s reading the same. No update, not connection. Could you please help with this?
