We always keep the profile up to date and update the profile no later than 30 minutes after the report is released, in case we have old and non-up-to-date data. It is therefore possible that a profile has not had an update in the last few months because it has not been requested by our customers. For this purpose, we have included the message "Report is up-to-date" in the Audience Report to give a clear indication that the data is up-to-date.
Thus, we always recommend waiting until it is indicated that a profile is current. In most cases, the data changes only slightly. However, if the data changes a lot, it is possible that many (often fake or mass) followers were lost or removed during this period, or many followers from a different target group were added.
