iOS Share Extension works when accessed from Photo Gallery but not in ScreenShot thumbnail view.

I'm working on a share extension and it works when being accessed when selecting a Photo from the Gallery, tapping the share button, and proceed to tap on my app. The view controller executes code and everything is good here.

When I take a screenshot, tap on the thumbnail preview, tap on the share button, tap on my app, no code is fired off from the ViewController.

What is happening here?
