Alerts do not work on products with variations.

Hello. I will use the plug-in with variations.
I manage inventory for each variation.
“Stock alert” is displayed on the parent product when there is no stock of all the variations.
When you register “stock alert” with the parent product, an alert mail is sent to customers when products with variations arrive again.
When you register “stock alert” with a product with variation, an alert mail is sent to the customer.

I want to avoid displaying “stock alert” on the page of parent product.
Or, when you register ‘stock alert’ on the page of parent product, I wish to receive alert mail to all customers once products with variations arrive.

I do not mind either solution.

Thank you.
