Commented Unassigned: Unable to publish in reply to [2554]

I had the above mentioned working before and all of a sudden it has stopped. My code for replying to the tweet is as follows:

var newTweet = Tweet.CreateTweet(message);
var result = newTweet.PublishInReplyTo(tweetId);

The result is returned as false. Is there a way to figure out why?

Thanks for the feedback. I hope you will be able to make your application works as you wish.
In the meantime, I am closing the bug as there is nothing I can do in the library to help you.

Please feel free to post in the discussions ;)
Cheers,
