The MGTwitterEngine's sendUpdate with the inReplyTo parameter is not actually replying to a tweet and is instead tweeting a new one!
I faced the long long value problem as discussed in the forums, but I fixed that and the tweetID remains constant across. But whenever I reply to a tweet, when I check the twitter page, I'd have just tweeted a new one, instead of a reply.
Please do let me know what I can do to fix this problem!
Thank you so much in advance!
