We are having an issue with links that I am including in the message of the status update not generating link previews for the tweet. Both tweets/examples were created in the same way and have the link in the message, but have different results on Twitter. Example 1 does not have a link preview, but includes the link the text of the status. Example 2 does have a link preview, but the link was removed from the text of the status.
Why would one tweet have a preview and the other would not?
