Android 6.0 on Nexus 6 not allowing swipe from bottom right and left

I just installed Android 6.0 on my Nexus 6 and yet after watching videos of features of Marshmallow, I find that I cannot swipe to activate the camera from bottom right or the phone from bottom left. What am I doing wrong or are there switches I need to activate so these actions function?

unlock with swipe along the edge

Hi guys,

I'm asking if there is a feed or something other for edge screen features to unlock my phone swiping along the edge screen...I already use this feature to see notifications and news, but I want to know if I can use this swipe just to unlock my phone...

Anyone can help me? Thank you:)
