I try to read a document that exists in the firestore, but it always doesn’t. I also checked the rules and they are good.

  _checkOffer = true;
            var document = FirebaseFirestore.DefaultInstance.Collection("limitedOffer").Document("car");
            var checkIfExistDocument = document.GetSnapshotAsync();

            yield return new WaitUntil(predicate: () => checkIfExistDocument.IsCompleted);

            try
            {
                DocumentSnapshot snapshot = checkIfExistDocument.Result;
                //_limitedCarOfferData = snapshot.ConvertTo<LimitedCarOfferData>();
                Debug.Log(snapshot);
                Debug.Log(snapshot.Exists);
            }
            catch
            {
                _limitedCarOfferData = null;
            }

I tried to change the rules, I tried to create another document, but so do
