@VaniBhemarasetty  Thank you for the info. As a follow up question I want to ask what happens to previous app visitor IDs if user reinstalls the app on the same device. Would I still see the previous app visitor ID in adobe analytics data for the same device as you mentioned they persists on device ...

@Andrew_Chepurny What would be a Unique visitors definition on mobile apps? If user log in from one device it a unique visitor and if logs in from a different mobile device is it a second unique visitor? The number of unique visitors in mobile world would mean number of active devices?

 did you find the answer?
