The dispatch date that we set on the order in Linnworks does bizarrely not get passed over to the courier on the JSON? isn't this the most important piece of data surely?

We now have to do yet more workarounds to create an extended property to handle this date. 

Linnworks is great platform, with lots of flexibility at least, but it has so much more potential if the documentation and issues like this were addressed fully.
