Edited Unassigned: Image upload not working [2254]

Hi,
I'm trying to upload image from my WP8 app to Twitter and it worked well but from yesterday I can't post images with success. I'm using this code:
```
var file = ToByteArray(image); // Method to extract byte[] from a file on WP
var t = Tweet.CreateTweetWithMedia(text, file);
var success = await t.PublishAsync();
```

What can I do? This app is really important and users are complaning about this issue.

Thank you,
Alessandro
