Ever since we upgraded to Woocommerce version 3 our order confirmations are showing huge titles that include the variation detail. I don't like how it looks and it breaks some important functionalities in some custom-made plugins.
Reference: Order Name Showing Variations since update to WC version 3
There is a filter that can be used to disable this data displaying in the title called
woocommerce_product_variation_title_include_attribute_name from what I understand. But I have no idea where to apply the filter.
Is there a quick way to apply the filter to change it back to display as it did before?
