Hi all, reaching out here looking for some insight on a retention report. I'm plotting the Month 1 retention rate for user engagement on our website, using a calculation based on 30-day windows. When looking at the numbers for the previous month (specifically, users who signed up in May and returned to the site in June), I noticed that there is an asterisk denoting incomplete data for the month of May (see the screenshot attached). I'm using the "return on" option.Since the time interval is set between March 1st and June 30th, I expected the data collection for users who signed up in May to be complete. Does anyone have any idea why this is happening, or has anyone else come across this?
