A single product from my library did not get synced to Zettle, why?
- You did not set a price for the product. Products without a price are not valid for sale in WooCommerce and will not be synced to Zettle.
- Zettle only supports up to three product attributes (in Zettle: “variants”) for a variable product. Note that a Zettle variant can still have an arbitrary number of values, e.g. more than three colours to choose from.
