I raised a ticked for this in January and sadly still no further development "It's being looked into but no ETA as yet" - such a shame as to use tracked returns currently means logging into DMO each and everytime, taking up time and resources.
An integration from Linnworks would be most welcome (Especially since the large price increase ;-) )
this surely would be a welcomer feature. They said it would come this year.
We also really need this feature. Our Royal Mail Account Manager and Linnworks tech support both indicated integration due this year.
Are you able to create adhoc return labels in DMO, we only have the new service Click & Drop. It doesn't allow us to create ad-hoc labels it seems to need an order to work with in the first place.
