    Hi,

    in these weeks weàre updating a game that was released with Unity 5.3.8f1 (built with XCode 8.2.1).

    Actually we're working with Unity 5.6.3p4 and XCode 9.0. Testing with Testflight and Fabric Beta we've seen that updating the game the value of SystemInfo.deviceUniqueIdentifier results in different values.

    For each app version this value remains consistent, but changes everytime we install a different version.

    Any idea?

    I have the same problem with a Testflight update (from users with a previous Testflight version).
    The last 2 builds (the recently expired one and the new one) are the first I've been compiling through Xcode 9.

    Have you found out what is going on?
