[BUG] LUIS Authoring adding example throws exception

Describe the bug The adding example operation Microsoft.Azure.CognitiveServices.Language.LUIS.Authoring.Examples.AddWithHttpMessagesAsync method throws Microsoft.Rest.SerializationException exception. With message:

Unable to deserialize the response.
JSON integer 2148095092 is too large or small for an Int32. Path 'ExampleId', line 1, position 23.

Seems like an issue with response deserialization to LabelExampleResponse class, caused by the type of ExampleId property. The actual response content is:

{"ExampleId":2148095092,"UtteranceText":"test example"}

The ExampleId value 2148095092 > 2147483647 (Int32.MaxValue)

Expected behavior Executes successfully.

Actual behavior (include Exception or Stack Trace)

Microsoft.Rest.SerializationException
Unable to deserialize the response.
JSON integer 2148095092 is too large or small for an Int32. Path 'ExampleId', line 1, position 23

To Reproduce

var luisAppId = new Guid("590e74a6-4bb4-4729-8c78-7c53d7068750");
const string intentName = "B5578F30-59AA-4801-9A27-C73BB3C1C4FE";
const string versionId = "8.Rc";
using (var localClient = CreateClient(localApiKey))
{
    var example = new ExampleLabelObject("test example", null, intentName
    try
    {
        var exampleResult = await localClient.Examples.AddAsync(luisAppId, versionId, example);
    }
    catch (Exception ex)
    {
        Console.Error.WriteLine(ex.Message);
        throw;
    }
}

What is the status of this bug? We have just started to receive the same error this evening, and it was working fine earlier today (5 hours ago). We are using authoring resources in West Europe , and are now receiving the following error when using the Client.Examples.BatchAsync method (Microsoft.Azure.CognitiveServices.Language.LUIS.Authoring v3.1.0):

Microsoft.Rest.SerializationException: Unable to deserialize the response.
 ---> Newtonsoft.Json.JsonReaderException: JSON integer 2147569261 is too large or small for an Int32. Path '[0].value.ExampleId', line 1, position 33.

We have 3 environments, all authoring resources are in West Europe, and all 3 are failing - this is causing an issue for our live production software.

We have been using LUIS for the past few years, why would we have only started seeing this bug today?
