There are couple of reasons why the discrepancy between active/activated users might occur in the analytics.
For the whole synchronisation it could take up to 48h to refresh users and their activity in the analytics.
Specific of computation
Example of computation: let’s assume a fictional period of 10 days.
On day 1: there are 10 active users.
On day 5: 5 of these users get removed.
On day 6: 3 users get added that become active immediately.
On day 10: we are computing statistics.
Based on this input the final result is: active users: 13 and activated users: 8 which explains the discrepancy in the report.
