After you add a registry from another store, we sync it daily. That way, you and guests can see the latest pricing, availability, and more for all gifts from that registry on your Zola registry.
So if you add more gifts to your other registry after you add the whole thing to Zola, they’ll appear on your Zola registry after the next sync is completed. If you edit, delete, or adjust the quantity of gifts on your other registry, those changes will appear on your Zola registry after each completed sync, too.
