Sync between CRM, Campaigns and Survey not all working correctly

Sync between CRM, Campaigns and Survey not all working correctly

We have a Zoho Survey that is connected with Zoho CRM. When we send a Survey to a Contact from within CRM the Survey fields that already have data in the CRM are pre populated in the Survey and when the Survey is submitted any updates are also made in the matching CRM contact fields. This is all working well.

From the various documentations it appears we should be able to get the same functionality from a Zoho Campaign mailing if the Mailing List is a sync from a Custom VIew in CRM and we use an Advanced Campaign to select a Zoho Survey as the type. However when we do this this and click on the link provided to the survey in the email sent by Campaigns, the Survey displayed does NOT have the data from the corresponding CRM record prepopulated.

Is it not possible to use Campaigns to send CRM - Survey syncing surveys to a group of CRM contacts?
