Why can't I tag my products in Instagram posts yet?

Instagram product tagging needs Meta to approve your Instagram account for shopping, and that is Meta's own review, not something WCart can speed up. On the Instagram & Facebook Shop plugin page, the Instagram Shopping card shows whether the account is Approved for tagging and the Meta review status. If it is not approved, check Instagram Settings → Business → Shopping in the app or reapply. Once approved, you tag products from the Instagram app when creating a post, reel or story.
