I published 2 apps, both of which had Google Play Games Services integration. I tested the leaderboards and they worked.
Later, users found that the leaderboards weren't working. I checked, they weren't. I went to the dev. console and went to the Google Play Games section and I saw that all of my projects vanished. None showed.
I tried to recreate a project for one of the apps, but when I did the "Link an app" part of the setup, I got an error saying:
"Client ID is globally unique and already in use."
What can I do to get my projects showing in the console?
