If restarting Discord wasn’t enough to get the link previews to show up again, it is recommended that you check the application’s settings. Closing and then restarting the application is good enough for most users to get the preview to show up, and this should be the case for you. Open the specific chat in which you were sent the link and check if the preview is there or not. The first thing that you should try is to exit the Discord app and then open it up once again.

But there is a slight problem that sometimes occurs with these links, specifically with YouTube links. Nevertheless, it is still pretty handy and is definitely a great addition to Discord. This is a pretty basic feature that most applications have, meaning that it isn’t quite as unique as most of the other features that the app features.
