This update, made big mistake on my bundles products. All of them passed out of stock.
This is because, all products with variation don't have to be "manage stock at product level" and when i did "Tools and Update WC's Manage Stock," it passed all products with variation on "manage stock at product level".
So i found the solution but it was hard to find why all my bundles products was out of stock, while the products inside it were on stock.
Otherwise, i still have the same problem, when i add stock directly from "stock central" the statuts "stock selling manager" stay in red. I don't have this problem whn i add products from "purchase orders"
