On Feb 13, 2018, it was discovered that our analytics server was not properly responding for data after the date of February 7, 2018. As a result, numbers of Opened Widgets, Interacted, Add to Carts, Conversions etc. were less than they should have been. This issue was resolved on Feb 15, 2018 and further checks put in place to mitigate future cases. We re-ran all analytics reports that occurred in this erroneous time period, but did not re-email those reports (they are always accessible via the Reports section).
Any analytics viewed between this erroneous time period, if recorded, should not be used. Instead, please visit the same time frames again, and the data should be trustworthy.
To clarify, no data loss occurred. But during this time period the analytics server was not properly observing all stored data.
