I tried to configure tracking url pointing to author instance in the publisher instance..
http://<host>:<port>/system/console/configMgr/com.day.cq.wcm.core.mvt.MVTStat istics
http://<host>:<port>/system/console/configMgr/com.day.cq.wcm.core.stats.PageV iewStatistics
But when I click the pages on publisher instance the statistics are not updated in author env multivariant testing component configured.
