Snapchat not notifying people of screenshot?

[Dyingpie1]

Hey guys,
For some reason whenever I screenshot something it doesn't notify the person that I screenshotted it. Any idea why that is causing this?

I have an HTC one m9 with stock software.

Is it supposed to notify the sender?
(Obviously I am not a Snapchat user.)
