We are getting errors constantly about unified native ads that Google kind of newly introduced and this is the documentation link. At least 0.2% of the errors are from this situation so it actually is important and I don't think it's a bug in the SDK as well, because I didn't find any questions or discussions about it. Also there is nothing noted about this in the documentation. Here is the stack trace:
Fatal Exception: java.lang.IncompatibleClassChangeError: Class 'com.google.android.gms.ads.internal.client.m' does not implement interface 'com.google.android.gms.ads.internal.util.f' in call to 'void com.google.android.gms.ads.internal.util.f.a(java.lang.String, java.lang.String, boolean)' (declaration of 'java.lang.reflect.ArtMethod' appears in /system/framework/core-libart.jar)

Now, let me cover some things up about the details about it as I cannot share any source code about this:
- This exception is thrown in devices that has API 22 only.
- Our application uses proguard and it does not have a specific setting about keeping the classes of native ads. (I don't think this is the issue because of specific API errors only, and the SDK is already obfuscated in itself.)
- We are loading ads in the application class and show them almost immediately when the related screen opens (it mostly has a delay of 150ms.)
Does anyone have facing the same issue? Or can you suggest a workaround for this kind of error? Any help is appreciated, thanks.
