问题
I'm trying to activate firestore on a project on which I'm not using AppEngine nor Datastore and having this error message.
Cannot enable Firestore for this project Currently Firestore cannot be enabled in projects already using Cloud Datastore or App Engine
To be more precise, I used to use datastore but now there is no entities in my project datastore. So maybe there is something that I need to disable explicitly
Thx in advance for your help

Unfortunately since you have previously used Cloud Datastore in that project, you cannot create a Cloud Firestore instance. Our ability to switch it currently only works if it was never used in the past.
