how to detect if the user is still signed in?

[Midjiwan]

If a user signs out of Google Games Service through the interface at the native Achievements display page the ANE does not seam to recognise that. Is there a way to check if the user is still signed in? running getActivePlayer() returns a valid player even if they are signed out, and calls to for example getPlayerStats() will not do anything (not even trigger an error event).

I got a change request from Google regarding this issue so it is of course very important for me to fix. Any help appreciated.
