    Hello,

    I'm using Unity Ads 3.4.1 (from the asset store) and I have an issue for which I couldn't really find a solution. I tried to display an ad on an Android 4.4.4 Kitkat phone and the game crashed. I looked up in logcat and found the following :

    I tried with a more recent phone Android 8.1 Oreo and it worked just fine.

    After many hours of trying to figure out what was the problem (Creating empty projects which worked just fine) I disabled code stripping and Unity ads were finally working.

    Since Unity Monetization comes with a link.xml file I guess it should not be a problem.

    To sum up I don't really know if this is a bug on Unity Sdk side or if I'm missing something.

    I could use a bit of help here :)

    Thanks in advance
    Valentin
