[Bug] PutStreamAsync is never completed if there is no internet connection

• Unity editor version: 2019.4.21f1
• Firebase Unity SDK version: 7.1.0
• Source you installed the SDK: .unitypackage
• Problematic Firebase Component: Storage
• Other Firebase Components in use: Auth
• Additional SDKs you are using:
• Platform you are using the Unity editor on: Windows
• Platform you are targeting: iOS, Android
• Scripting Runtime: Mono and IL2CPP

I am using Firebase Storage and currently having an issue using PutStreamAsync when there is no internet connection. It seems like the task will never complete, even though I reduced MaxUploadRetryTime to 1 second or got the internet connection back. Task.Status is always WaitingForActivation

var task = storageReference.PutStreamAsync(ms, new MetadataChange()
{
    CustomMetadata = GetMetaData()
}, null, CancellationTokenSource.Token);

Editor log:

ApplicationException: GetFutureStatus(handle) == kFutureStatusPending
Rethrow as ApplicationException: backing->status != kFutureStatusComplete

Hi,
Thanks for creating this issue. Could you verify if this is reproducible in the Unity quickstart example for storage?

@vimanyu Last time I checked, storage example still has this issue

Hi @dacodelaac,

For our reproduction puposes, could you tell us which platform(s) this occurs on?

Thanks!
