Is there any way to change the container volume after the products have been set up?
You should be able to change the taxable volume, but not the gross volume.
However, we can potentially do this for you (depending on how the products using the container type have been used so far). If you open a support ticket to grant us data access, let us know which container type(s) you’d like changed and the volume you’d like them changed to, and we’ll see what we can do for you
