As of February 19th, 2021, Product Builder is unavailable for new installations. If you are currently using Product Builder, you will be able to continue using the app as your account will now be grandfathered.
If Shopify asks you to remove an item from the cart or checkout page, it is possible that the item either:
- Has no available stock.
- Is not available on the Online Store sales channel.
In order for Bold's Product Builder to function correctly within the cart and checkout, you will need to make sure that the product(s) you are selling in your Product Builder product have ample stock and are available on the Online Store sales channel.
