Problem
An anonymous user profile is created containing only an uninstall event. It contains no actual user information and does not map to a registered profile.
Solution
Perform the following steps:- Expand the uninstall event in the Activity info to check for campaign details.
- Locate the Campaign ID associated with this event.

- Search for the Campaign ID in the dashboard.
- If the campaign was scheduled for All Users, it indicates that the user had uninstalled the application before the campaign could be delivered.
