Just kind of a stupid question, but why on the new built-in instagram the dm icon doesn't appear for me?

Hey opera community, I've been having this trouble quite frequently but haven't come across a solution, even though I have the latest flash player installed on my mac at all times, every now and then when I install a new opera version most of the times, I get a grey screen on a flash player and is doesn't let me reproduce the video, sometimes it fixes itself when there's a new version for the browser and sometimes not, its mostly random, I don't know what causes it and what fixes it, it's getting REALLY annoying and that doesn't happen with ANY of the other browsers I have: Chrome, Firefox, Safari or Vivaldi, thanks in advance
