Proguard + Plugin time cheat (unbiased)

Unity Engine
,
1

Hi! i have the unbiased plugin for unity but cannot find where to submit an issue.
I was trying to use proguard with this time cheat asset, added this code in proguard plugin android txt
-keepattributes *Annotation* -keepattributes SourceFile,LineNumberTable -keep public class * extends java.lang.Exception -keep public class UnbiasedTime -keep class com.crashlytics.** { *; } -dontwarn com.crashlytics.**

But i have this error that i can see in unity cloud
java.lang.ClassNotFoundException: Didnā€™t find class ā€œcom/vasilij/unbiasedtime/UnbiasedTimeā€ on path: DexPathList[[zip file ā€œ/data/app/com.IndieFist.RequiemforerichSann-MlYgc81SIFnfOvaLdMcKSg==/base.apkā€],nativeLibraryDirectories=[/data/app/com.IndieFist.RequiemforerichSann-MlYgc81SIFnfOvaLdMcKSg==/lib/arm64, /data/app/com.IndieFist.RequiemforerichSann-MlYgc81SIFnfOvaLdMcKSg==/base.apk!/lib/arm64-v8a, /system/lib64]]
dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:134)

This problem is only when using proguard, how can i exclude this plugin from proguard?
also i have to add some in every class that are using this asset? or in the main class?

I have added this two lines but still same crash in unity cloud, in game is working fine.

ā€œunbiased plugin for unityā€ do you have the asset store link? You likely want to contact the developer who should be listed there.

They dont know what to do, but give this step:
I donā€™t know, maybe try replacing ā€œ-keep public class UnbiasedTimeā€ with ā€œ-keep class com.vasilij.unbiasedtime.UnbiasedTime.** { *; }ā€

And now i have this error:
Managed Stack Trace:

java.lang.NoSuchMethodError: no static method with name=ā€˜vtcOnSessionStartā€™ signature=ā€˜(Lcom.unity3d.player.UnityPlayerActivity;)Vā€™ in class Lcom.vasilij.unbiasedtime.UnbiasedTime;

com.unity3d.player.UnityPlayer$e$1.handleMessage(Unknown Source:88)
android.os.Handler.dispatchMessage(Handler.java:102)

vtcOnSessionStart is inside UnbiasedTime.cs and its under #if unity_iphone statement, could be this the problem?

Well I havenā€™t found any solution jet.
How can I exclude this class without having null reports?
Maybe do I need to exclude also my main class? this one where is referenced to use unbiased plugin?
Can I exclude my class by this way?
-keepclasseswithmembernames class * {
native ;
}

Have you got their examples to work? That would be my first step.

Sorry for bump this thread, but i was fixed and is working with:
#unbiased
-keep class com.vasilij.unbiasedtime.** { *; }

I just used in another project, found the same problem and this thread lol.
Is a really good plugin and is working fine, but have bad reviews in the store:
