Scene doesn't unload while using Unity Framework on iOS

I’m using the following code to load/unload scene. I’ve a simple setup of two scenes and I’m switching between two scenes.

public static void GoToScene(string sceneName) {

It works as expected in Unity Editor, However, when I export it for iOS Unity Framework and run the app on phone it doesn’t work as expected.

Any solution or ideas to solve this would be highly appreciated.

To the root, I assume this is a relevant issue.
