Hi All,I am having trouble calculating 2018 Unique Visitors broken down
by return visitors attributable to 2016/2017 and new visitors for
2018.Does someone have a way to calculate this? My issue is really with
breaking down 2018 by return visitors attributable to 2016 and 2017. AKA
how many users in 2018 were also users from 2016 and 2017?Caveats:
Unable to use IP address or Visitor ID.Thanks!
