Errors when the Internet is weak in Unity SDK

已于 2024年6月25日发布

Hello guys!

We have integrated Zendesk SDK in our Unity project, and then we started to get errors if we tried to close the Zendesk popup with a weak Internet connection while running ZendeskSdk.Instance.Messaging.ShowMessagingAsync(). It looks like we need to pass a CancellationToken to the function arguments to force the coroutines to terminate.
