@Rich Owings, I've seen that before. Some Analytics data got wiped out earlier this year, when Google's data-retention settings changed. What you might find in various views in GA is that data older than 26 months is gone.
Good catch. Sure enough, when I check the setting, data retention is set to 14 months, and I can't see traffic before Aug. 25, 2017. It's just strange that I can see other, earlier traffic until I display the organic segment.
