Active users duplicated on iOS (not on android) in Firebase from last one month. Ex: For One userID with the report is showing Total users:2 and Active Users: 3 with different device types like
3 different device type and 3 active sessions showing in the report. Ideally it should be One userID, One device and One Session.
How to further investigate this issue.

Compared reports for last 3 months and found that for example for the same UserID, Total users:1 and Active Users:1 which is correct. and now its showing same UserID Total users:2 and Active Users: 3
