I'm developing a Xamarin Application using Google Firestore as db. I connected my app to db by setting GOOGLE_APPLICATION_CREDENTIALS as Environment Variable but when I try to read data from db I get this error:

Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Bad gRPC response. Response protocol downgraded to HTTP/1.1.")
  at Grpc.Net.Client.Internal.HttpContentClientStreamReader`2[TRequest,TResponse].MoveNextCore (System.Threading.CancellationToken cancellationToken) [0x00406] in /_/src/Grpc.Net.Client/Internal/HttpContentClientStreamReader.cs:194

and this is the code I'm using

QuerySnapshot querySnapshot = await databaseFS.Collection(myCollection).GetSnapshotAsync();

Is Xamarin compatible with Google.Cloud.Firestore and Google.Cloud.Firestore.V1? If yes, why I'm getting this error?
