Why Is Only One Pre-order Product Added to the Cart?
If you're only able to add one pre-order product to the cart, it could be due to the following reason:
Old Pre-order Model with Discount or Partial Payment Enabled When using the old pre-order model combined with Discount or Partial Payment features, the system is limited to processing only one pre-order product at a time.
Additionally:
Clicking the Pre-order button in this setup will redirect customers directly to the checkout page, bypassing the cart. This prevents multiple pre-order products from being added together.
✅ Tip: If you want customers to add multiple pre-order items to the cart, consider switching to the new pre-order model without enabling discount/partial payment features or contact support for a solution
