Slack – How to re-enable link previews in Slack

slack

At some point I disabled website link previews from YouTube in our Slack team. But this was a huge mistake, we need them back. How do I re-enable link previews for a specific website that was disabled, or for all websites?

I have already disabled / re-enabled all preview types under Preferences > Messages & Media, but YouTube is still disabled.

Visit https://[TEAM].slack.com/admin/attachments as an admin or owner of the team. Then simply click the X on all the website link previews you want to automatically "unfurl" again.
