Attribute filtering doesn’t seem to work

Hi,

I am trying to setup a filter so that if a product has the attribute “dangerous-goods” set to “Yes” it applies a different Shippit shipping method to the cart. But your filter by attributes doesn’t seem to be working.

I have 2 Shippit shipping methods assigned to my zone.

For both I have “Filter by product attributes” set to “Yes”, I have “Filter by attribute code” set to “dangerous-goods” and for one shipping method I have “Filter by attribute value” set to “Yes” and for the other I have the value set to “No”. So theoretically if the product has this attribute set to Yes or No it should change the shipping method accordingly, but it’s not. Can you provide an example of this working so I can emulate this because I suspect this feature just doesn’t work.
