We have setup 2 delivery areas. 1 free area and 1 area they have to pay.
The second area surrounds the first area.
The majority works however postcodes in 2 areas seem to give the wrong results even though they are set correctly according to google maps.
So some postcodes in the free area are charging and some postcodes in the paid area are acting like they are in the free area and not charging.
Has anyone else had this issue and if yes have you found a fix for it.
Any help greatly appreciated.
