Instagram decrypter seems doesn't work anymore.
It seems JD always remove '/' at the end of url. And Instagram always redirecting this url to the right url with '/' on the end. But JD doesn't following this redirection. So it just appear offline on JD's LinkGrabber.
Example links:
**External links are only visible to Support Staff****External links are only visible to Support Staff**
Instagram also redirect single post url, fortunately JD follow this redirection. But it's better if JD add those '/' at the end. So there is not much unnecessary request.
**External links are only visible to Support Staff****External links are only visible to Support Staff**

Seems like JD2 isn't parsing Instagram at all anymore, it usually finds all images and videos, but now it doesn't do anything. :(
