We've changed the "Product Inventory Quantity" (minimum/maximum inventory quantity) input fields in the conditions section of pre-order rules so that they only appear when the checkbox is turned on.

Previously, the inventory quantity input fields were always displayed, which sometimes led to values being entered unintentionally, preventing "Robust restrictions on the checkout page" from being enabled. With this change, the input fields no longer appear for rules that don't use the inventory quantity condition, preventing conditions from being set by mistake.
What Changed
- Display method: Input fields always shown → Now shown only when the "Sell based on product inventory status" checkbox is turned on
- Placement: Moved from above "Customer information" to below "Customer information" (the end of the conditions section) within the conditions section
- Notice: Added a note explaining that setting an inventory quantity condition will make "Robust restrictions on the checkout page" unavailable
If you have already set an inventory quantity condition in an existing rule, it will open as-is, with the checkbox on and the input fields displayed. There is no change to how the values are retained or how the condition itself behaves, so no additional setup is required from store owners.
