Double tap to sleep home screen not working

[juniormarbles]

Followed the prompt and set the switch to "on" .

Does this feature only work if lock screen/password is activated (which I chose not to)?

Please advise what else I need to do to make this work.

@Marbles

Double tap is to wake up the screen.

..and since MM update to put it to sleep with the same two taps!

Except on my Z3C it's not working.

@Marbles This was made available on the concept only I think. Do you find this feature under home settings?

If not, it is not there for the compact on 6.0.1.

As moderator of this forum, shouldn't you know this stuff?

Under "Home Screen Settings" there's a switch option "Double-tap to sleep" which I turned on, but it does not work.

@Marbles I do not have any kind of information about change logs on updates. You don't need to be rude.

Try to go on the home screen and double tap to make it turn off.

There's no need for rudeness, especially when discussing features of software so new, there's no guarantee anyone in here would be up to speed regarding it's individual features.

I did not mean to be disrespectful when asking if, as moderator of the Sony-owned specialty forum about my phone, a forum I rely on for authoritative information, that moderator should know basic features of that phone or its operating system?  

I come here, because Sony points me to this site as its (sole?) customer support resource. If the Sony-appointed Xperia expert does not know some of the facts, say so, and no big deal. But I find it disappointing to so far get several erroneous answers without the expert/moderator correcting them, or indicating that futher research is on the way to eventually answer my simple question of how I can make that Xperia-specific feature work on my Xperia phone.

We are simple users sticking around to help, not employed by Sony. We get information just like you do most of the time, articles, xperia blog etc. But we will try to get further info on this. I am sorry you are not pleased with our replies.

And I am sorry if I mis-identified you as affiliated with or "in the official loop" with Sony. This forum is hosted on Sony's official website, which gave me the impression that its contents are authorized/monitored/contributed to by Sony employees. 

Is there another source I could access to get "inside" information about Sony Xperia MM features/implementations when they don't seem to work right?
