PreOrder Now Backorder WOD

App worked great for a while, after they made some updates we started having issues where some products in stock would show as out of stock with the pre-order buttons. After they made some changes, it seems like one of the settings made all of our out of stock products available for pre-order which caused us to have orders for discontinued products or products we could not get anymore. After that I used AI to build a pre-order tag within our own code.
