The alert with warning about possible lose of data is being displayed always for any app being installed from TestFlight. This was true for any of multiple apps I have tried. identifierForVendor changes when overwriting app with TestFlight build.

When you have App Store version of the app installed and overwrite it with build from TestFlight, result of UIDevice.current.identifierForVendor! changes

In my case unexpected change of identifierForVendor was causing "loss of data" which wasn't actual loss of data, but it is happening only for TestFlight builds which you cannot debug, so it was hard to find the issue.
