Currently when users update a segment it may look like this:
we found that it is not clear to users that after changing a segment definition, then they may lose historical data for their segment, and end up with only say 1 or 3 months of historical data. Some people got frustrated by this.
it would be valuable to better inform users of what's happening by doing the following suggested steps:
process_new_segments_from = "lastX"then also mention to users to make it clear eg.
Reports for this new segment will be available for the past 90 days.
process_new_segments_from, then also show a clear message eg.
Reports for this new segment will be available for the past 30 days (because visitor logs are kept <a link-if-super-user>for 30 days</a>).
as always, any feedback welcome!
