Last week, we improved validation for Product Bundles within the new Products section. Previously, the new section allowed users to set product quantities within a bundle to zero. With this improved validation, the minimum quantity is now 1 by default going forward.
If you have already set up a Product Bundle in the new Products section with a quantity of zero, you will need to go back in and change the quantity from zero to 1 to ensure optimal performance.
This is just one of a few updates to improve product bundles we have made in the past few weeks to ensure a smooth checkout experience for your customers.
