I no longer receive the web link previews in my message+ app when someone sends me a link. I have a galaxy S5.  And yes, I have the most updated version of message+ and my operating system. I have web link preview option turned on in my message+ settings and I have received web link previews in the past. I uninstalled all updates to message+ app to check if it was a problem with the Message+ application. This did not work. I have cleared cache and restarted phone etc.

An interesting observation is that any web links sent to me in the past (say 4 months ago) will unfurl and show the link preview when sent again. No new web link previews can be viewed, however, not even https://www.facebook.com. The text message appears as an enabled link but the open graph images for the preview do not appear.
