Google drive pdf embedding in rich text gives "no preview available" after a while of publishing. I delete and add the embed again with the same link and it works again, but after a while i check the page and i get a no preview gray box.
I just re-added the links in this page: http://www.cliniquedulevantsm.com/blog/world-osteoporosis-day-2016
But check this one, still no preview: http://www.cliniquedulevantsm.com/blog/financial-burden-of-cancer-drug-treatment-in-lebanon
Is it a Webflow bug or a Google Drive thing?
