Xamarin.Forms PCL Solution on Mac OS and XS 5.2.1 does not include Android Project

Hi,

I have a Mac with 10.9.4 on which I had installed Xamarin Studio with iOS support.

I upgraded it to 5.2.1 and I installed the latest Android SDK (23) in order to have Xamarin.Forms support and be able to test on Android.

In the preferences, I specified the Java SDK and Android SDK, with success.

When I create a new PCL solution, though, only the PCL and iOS projects are created (see screenshot).
The Android solution is not created.

In the Project options - Build - General, I have PCL 4.5 78, Windows 8, Xamarin.Android and Xamarin.iOS.

I don't try to add an Android project "manually" to the partial solution because of course the "classic" android project does not initialize Forms.

Can anyone suggest anything?
- reinstalling Xamarin? (I am afraid it may break older projects)
- clearing cache (how?)

Thanks a lot!
