recently I saw the following information about setting the unique ID for unique visitors in mobile apps.
"The SDK generates a unique visitor ID when an app is installed. This app visitor ID is stored within persistent memory on the mobile device and is sent with every hit. The app visitor ID is removed only when the user uninstalls the app (app visitor IDs persist through upgrades)."
It is accurate that a delete and reinstall of the app will cause a new visitor to be generated.
I need to clarify that while clearing app cachewill not cause a new Visitor ID to be created, clearing app datawillresult in a new Visitor ID being created. Also worth noting that the SDK uses no information about the device when generating the Visitor ID.
