Hi, @oscarfilhoo!
why do some products come with “sync and show” and others come with “sync and hyde” by default?
I know it can be confusing but, without more information on your products, it can be difficult to say. Are you seeing differences between the products that “sync and show” and those that “sync and hide”? For example, are some variable products, bundled products?
For instance, virtual products will be automatically hidden as they are not allowed by Facebook’s Commerce Policy.
Let us know if you can find some pattern in the products, and we might be able to help you figure out why some of them “sync and show” while others “sync and hide.”
