"Use Default Value" in standard is selected for all stores view.
In products --> Catalog I can switch store view example from default store view to English and then edit product and then in description uncheck "Use Default Value".
In single product I can switch store view:
But for above 11k products take more time. Any one know how to uncheck for all products description in one time?
@UPDATE
I will checked in database catalog_product_entity
and then try edit sample product.
