Breeze does not flush cache automatically in woo inventory sensitive eshop
When a customer buys an item, the product stock doesn't update if Breeze cache is not emptied. The item can't be added to the cart anymore since that request goes through the database, but could you update Breeze plugin to clear cache when a product changes (to remove bought products from lists on these pages if stock goes to 0) on purchase as well? Now cache is only cleared when updating the product, so changing stock amount by hand updates it even on cached pages, but buying product doesn't. At the moment Breeze can't be used on e-commerce sites where stock is important (unique products for example) because of this.
Other plugins (like litespeed plugin) already do this automatically.
The was fixed in 1.1.10 Please refer to our changelog for more details https://wordpress.org/plugins/breeze/#developers
