My Dynamic ship setup does not have the scale integration field. I have the latest version (2.5.7565.0) of Dynamic Ship and cannot figure out why I do not have this field. I have tried personalizing the page to no avail, the field is just not there.
We will be adding the ability to setup a scale through PrintNode in the next release, but there is no ETA. If you are interested in trying a pre-release copy, have your Business Central partner contact our support for an extension that will need to be compiled before using.
