Currently Magento Price sync works only if Magento is Integrated in
LinnLive and if there is a listing template for that Item in LinnLive.
Method which is invoked in Linnworks checks pktemplateid in
magento_templates2 table and if it is empty, then price sync fails. There are customers, which don't use Magento in LinnLive, so Magento price sync in Linnworks should also work without templates in Linnlive.
