Unique visitor inflation after upgrade

[christa_mabee]

We just updated an app from 1.2 to 4.0, and saw the number of unique visitors immediately spike at release. I'm trying to figure out why. 

We weren't setting the visitor id before, and aren't (intentionally) now either. To make sure I did a string search on the codebase and didn't find any references to visitorID in the previous implementation or to setUserIdentifier in the new one. We don't clear the SharedPreferences at upgrade, we update some of our own stored strings but those would be in a separate file from Adobe. ​

Can anyone think of something that might be inflating the unique visitor count?

I'm not understand too, but thankyou for this thread finally i get the answer, maybe something change on your referal web traffic.

That page describes web traffic, not app traffic, and this was around a release and not a holiday.
