can't find "my xperia" service/ app

[myrtw_hotmail]

Hello,

I am trying to find and activate the "my xperia" service allowing me to locate my phone or erase its content if lost. It's not in the Settings --> Xperia --> my xperia as it sould be because there is no Xperia in my Settings (!!!).

I recently upgraded my phone to the 15.4.A.0.23 version, and I should be able to find all that.

When I try yo go to the Update Center --> Apps, the phone is not showing the missing "my xperia" app as a possible update, while saying I am up to date.

I searched all of the applications from the application button, "my xperia" is nowhere to be found. But... and that's the most weird part, when I demand the list of all applications from the Settings --> Apps --> All, "my xperia" is in the list (!!) but with NO information whatsoever on the location of the app in the phone and NO possibility of opening or managing the application listed.

Any suggestions, you guys?

Please?

Either services is good but keep in mind that 

your phone has to be on

your data or wifi has to be on 

your gmail account has to be sync on the phone 

google location services has to be on
