The errors on the new daily spinner as seen on staging.gsn.com are occurring because GSN is only making one ad call but trying to display the same ad multiple times. Because reward confirmation is tied to a particular adInstance, this breaks both Volume 11 and MediaBrix ads. To correct the issue, a separate loadMediaBrix ad call should be made for each placement. For clarity, it is recommended that a unique adInstance name and adVerification callback be defined for each placement.
