Set Resolution not working on iOS with Unity 5

Hi,

we're just in the process of porting our Unity 4 project to Unity 5. In the old project we have a option to run the game in half resolution (uses Screen.SetResolution). It worked very good in Unity 4 and still works for Android in Unity 5. However in iOS and with Unity 5 this option does not seem to work anymore.

The app does not crash, but does not refresh the screen anymore. If I hit the position of the respective toggle again (full resolution), then the screen is refreshed again....
