I know this question have been answered here on stack overflow, but in my case, I have a project in my google developer console named "firebase-demo-project". In this same console, I cannot delete the project : it seems I don't have de right permission to do so (the delete options are grayed).
On the other side, in the firebase console for the same user, I have no project at all. So I cannot just delete the project from firebase since it's not there.
Anyone can help with this ?
