Answer 1

I had a problem that Firebase Remote Config didn't fire OnCompleteListener with fetch(0), but with fetch() did.

Looking at FirebaseRemoteConfig.fetch() does not trigger OnCompleteListener every time, I found that the first answer was working sometimes even with fetch(0). Then I again set 3600 seconds for interval, as errors continued to appear:

override fun onPostResume() {
    super.onPostResume()

    // Initialize FirebaseRemoteConfig here.
    ...

    firebaseRemoteConfig.fetch(3600).addOnCompleteListener { task ->
        if (task.isSuccessful) {
            firebaseRemoteConfig.activateFetched()
            //calling function to check if new version is available or not
            checkForUpdate(currentVersionCode, firebaseRemoteConfig.getString(VERSION_CODE_KEY))
        } else
            Toast.makeText(this@MainActivity, "Someting went wrong please try again",
                Toast.LENGTH_SHORT).show()
    }

}
