In Piano Analytics, we favour a tag-first approach and campaigns can therefore go up without prior declaration, which was not the case for the Analytics Suite 2.
Therefore, when the campaign prefix does not correspond to any known type (sponsored links, emailings...), the campaign will be classified in an "Unclassified Campaign" source. It is therefore normal that the traffic will come up in Piano Analytics but not in the Analytics Suite 2. On Piano Analytics, the uniqueness of a campaign is only done through its label.
