Thanks @jennifer_dungan , but if you see screenshot above (for 1st row of each device type breakdown), for e.g "Oppo A55" we are seeing 61 UV against 1 Customer ID. In single month its hard to believe that much re-installations.
Could these be from your internal QA and Developers testing the app? I get data like that from my team (and technically myself for UATing) since we are constantly uninstalling and re-installing the app (we both update and full delete). Particularly when we have to move from Dev build to Prod build.... as some of the settings get messed up if we attempt to upgrade between build types.....
It's for this reason I try to encourage most testing to be done on our Dev builds which are connected to a Dev suite. It should be noted, even when a mobile device is being used on an internal VPN, your don't see those IPs from the testing device, but you still get the mobile devices network IP... so your internal IP filters won't work.... of course, the Prod builds still have to be tested, so we always get a some testing data into our suite that I can't rid of....
