title: Sharing Image on Twitter via UIActivityController is not working
body: <p>We are developing a feature in our app in which we are trying to tweet an Image. When the app is installed, in the preview of the tweet, the image is not shown. While if the app not installed, it shows the image thumbnail in the preview of the tweet. Also in the installed app case, the tweet doesn’t get posted as well. Posting some screenshots for both scenarios. Wanted to know if the problem described here is related to the issue pointed above and what are the updates on the issue.</p>
