Why is my Lumia 920 taking time resuming everytime?

[WPCentral Question]

My Lumia 920 is taking time "resuming" everytime i press the button to wake up the phone

This has started happening a few days after upgrading to 8.1 and happened around the same time my facebook app greyed out and would not work at all. I have since deleted the facebook app and reinstalled and it is working fine but I am still getting a black "resuming" screen for about 5 seconds everytime I press the wake up button before I can even unlock my phone. I have tried turning my phone off a number of times but no luck there. Any suggestions on what might be causing this?

You probably would have found the fix if you had searched.

Go enable kids corner, then disable it.
Its caused by some remnants of the live lockscreen app being left behind.
