@ricard @null @ruud I saw this issue pop up a few weeks ago and I ran a test with both short and long links. Some were saying only certain links were previewing. Both previewed ok for me, and others, and still do, while some, many, viewing my posts didn't get a link preview via their instance.I surmised it was either an instance being behind on SideKiq jobs or having failing jobs or YouTube blocking and leaned towards YouTube as the root cause.
