LDS Tools Android Not Syncing

I have a Samsung Galaxy S2 smartphone (Android) and have installed (and reinstalled) LDS Tools.

I log in with my LDS Account and it goes through, pauses to scan, but after awhile I get the error "LDS Directory Services Not Available. Please Try Again Later." I have never been able to get LDS Tools to work since I have installed the app.

The same thing is happening to me. I have an android HTC. Did it ever work for you?

I was able to sync since some months ago with my Android 2.1 Tablet.
The problem I have is: "Connection lost" after correct login and the first unit name appear over the process bar.
