It is now possible for anyone to reconfigure their Facebook Ads sources, regardless of how much historical data is in the source.
Earlier a reconfigure was only possible if Funnel could replace all historical data, i.e. the "from" date of a source was less than three years back in time.
This change means it's possible to remove older data on a reconfigure. Based on the feedback of our users, we came to the conclusion that this is often perceived as a reasonable tradeoff. A warning will be displayed to reduce the risk of this happening by accident.
