Lock and erase options not appearing in Android Device manager My FairPhone appears in the Android Device Manager, its location is picked up, and I can ring it:



As you can see the separate Lock and Erase options do not appear as illustrated in the help:



If I click the Setup lock and erase the website says it sent a setup notification. I do not see anything arriving on the phone.

On the phone I have turned on both Remotely locate this device and Allow remote lock and erase options as described here.

In the play store, my device is set as 'Visible in menus'.

FWIW, I'm not signed in to Google+.

What am I missing?

Device: Android 4.2.2 'JellyBean MR2' / FairPhone 1.1 'Caju'. Not rooted.
It is now the morning after the evening I wrote this question. My Lock and Erase settings are now automagically present in Android Device Manager.

I have not changed any settings or powered off the phone, it was just 'sleeping' last night.

So it looks like the Google servers needed some time to enable the settings.
