There are users whose details are recognized but have minimal evets with them.
There are unidentified users with who have performed a large amount of activity (events), but yet not tracked (user details)
i have attached images showing the details that i have stated above
there is also an issue that it is not that only user distinct id or user name is missing instead i am missing other properties as well like country, their activity times, region, city. when i look into their event properties i am able to see their event properties like country, activity time, region, city
if the user is not identified with their username or the distinct id we have provided or email, they should be able to carry those details like their activity time, country, region, city as they are recorded in their event as they can be same
