Firebase - RemoteConfig with userProperty returns default value

Question

First I apologize for my English :-) I am working on a big project and I encountered a problem with using Firebase in my Android app. I have RemoteConfig with conditions using Analytics user property. When I set user property in app, fetch data and after it's successfully completed, I activate fetched data, I still get default value for parameters from RemoteConfig, even when RemoteConfig condition is true. Code is written in Kotlin.

This is an example of my code (this code is in onCreate() method in class, which extends Appliaction class:

FirebaseAnalytics.getInstance(this).setUserProperty("testprop", "a");
FirebaseRemoteConfig.getInstance().fetch(0).addOnCompleteListener {
    if (it.isSuccessful) {
        FirebaseRemoteConfig.getInstance().activateFetched();
            val a = FirebaseRemoteConfig.getInstance().getString("test_param");
            Log.i("TOAPP", "Test param is $a");
        } else {
            Log.i("TOAPP", "Error: ${it.exception?.localizedMessage}");
            it.exception?.printStackTrace();
        }
    }
}

RemoteConfig in Firebase:
Parameter = test_param
- MyUser = develop
- Default value: = production

Condition:
MyUser - applies if User property testprop exactly matches a

When I run this, I get this in console:
I/TOAPP: Test param is production

I have these libs in gradle.build file:

// Play services
implementation "com.google.android.gms:play-services-location:11.4.2"
implementation "com.google.android.gms:play-services-maps:11.4.2"
implementation "com.google.android.gms:play-services-base:11.4.2"
implementation "com.google.android.gms:play-services-identity:11.4.2"
implementation "com.google.android.gms:play-services-places:11.4.2"

// Firebase
implementation "com.google.firebase:firebase-core:11.4.2"
implementation "com.google.firebase:firebase-config:11.4.2"
implementation "com.google.firebase:firebase-messaging:11.4.2"

Thanks for the answers.

Is there a typo in your post (or code)? In the post, the text describing the condition has property name testprop: applies if User property testprop exactly matches a. In the posted code, you are setting property testparam. — Bob Snyder
Yes, there was a typo... I set user property testprop. I repaired post. But code still doesn't working. — TomasBiesok

Problem solved!

In Firebase, I have two Andorid apps (old app version and new app version). The old app works correctly, but with the new app were problems. When I opened old app in Firebase Analytics and then user properties, there were parameters which I use in remote config conditions. When I switch app to new version in Firebase Analytics, the user properties were empty. I added same properties from old app version to new app version in Firebase Analytics and new app works correctly.
