Hey, @StefaninoBCN .
Thank you for reaching out and posting this question.
If you’ve just linked your Facebook or Instagram accounts to Shopify, then it can take up to 48 hours for the Meta team to review your products. We also have a guide that can help with linking Facebook and Instagram right over here: Facebook and Instagram by Meta. That being said, it’s also worth noting that we’re unable to provide account-specific support via the Shopify Community. However, if the problem continues to persist, then we’d be happy to continue assisting you through live chats. Simply visit the Shopify Help Center and login to your account to create a support request.
If you have any other questions on this topic, then don’t hesitate to let us know.
