Hi, for some reason our unity data regarding new users and usage frequency (MAU/DAU) seems to be completely inflated, when compared to data provided by google and apple. I would of course expect some differences. But in our case unity reports 4 times the number of new users when compared to the downloads from apple and google. The MAU/DAU reported by unity is off by a similar factor compared to apple and google data. Did have anyone have similar problems/ do you have any ideas how such a difference could be explained? My only guess is, that for some reason the local device ID used for unity analytics get reset on a regular basis, so the same user is registered as a new one. But I wouldn’t know, how that could happen so often.
The analytics Id is Guid.NewGuid() by default, so it gets regenerated on reinstall, or anything else that clears PlayerPrefs. While we do see different numbers (we solve this by using our own Ids for our own dashboards), we do not see anywhere near as extreme differences as you, could you check if there is anything in your game that could cause PlayerPrefs to be cleared on a regular basis?
If your game has any kind of login system, you can initialise analytics with a hashed version of that to maintain Ids.
