I am having trouble getting links to show up with a preview in my group chats when sending a message from an email.

The exact same message being sent from the same account shows up differently when posted.

Ex. if you paste "http://www.orimi.com/pdf-test.pdf" on any chat when using Glip app, the preview of the test.pdf would appear, however if it was delivered "via email", it would only display the link.
