How to disable Google Fit and revoke permissions from the app itself

Question

I've setup app that connects to Google Fit, reads and writes some data about users body. When user disables Google Fit in apps settings, I try to revoke my apps permissions for by calling:

public void disableGoogleFit(){
    if(!mClient.isConnected()){
        Log.e(TAG, "Google Fit wasn't connected");
        return;
    }
    PendingResult<Status> pendingResult = Fitness.ConfigApi.disableFit(mClient);

    pendingResult.setResultCallback(new ResultCallback<Status>() {
        @Override
        public void onResult(Status status) {
            if(status.isSuccess()) {
                Log.i(TAG, "Google Fit disabled");
            }else{
                Log.e(TAG, "Google Fit wasn't disabled " + status);
            }
        }
    });
}

Even though I could successfully read/write data, disabling Fit returns me error:

Google Fit wasn't disabled Status
{statusCode=unknown status code: 5010, resolution=null}

Edit1: Added whole method, in which its visible, that client is connected at the moment I try do disable Fit.

Currently with 15.0.1 lib it can be easily done:

fun disconnect(context: Context) {
    val fitnessOptions = FitnessOptions.builder()
            .addDataType(DataType.TYPE_WORKOUT_EXERCISE, FitnessOptions.ACCESS_READ)
            .build()
    val signInOptions = GoogleSignInOptions.Builder().addExtension(fitnessOptions).build()
    val client = GoogleSignIn.getClient(context, signInOptions)
    client.revokeAccess()
}
