I have just set up a CubeCart account, and have linked it to a PayPal Zettle account. When I perform a sync, the product from the CubeCart account will be exported to the Zettle account, but the products in the Zettle account will not export to the CubeCart account. Additionally, when I change the quantity of the exported product in the Zettle app, it does not update the quantity of the product in the CubeCart account. I saw a similar issue with WordPress due to tax information not being setup, but I have setup the tax information for products in both accounts.
