Trello slack integration no longer unfurls from private boards (Documentation is wrong?)

Question

We have a private Trello board linked to a private Slack channel. I am able to do things like create cards, get notifications, Butler connections, etc in Slack.

According to the documentation, we should be able to use

/trello url-to-card-or-board

to have links to cards unfurl automatically in Slack.

When I try this in Slack, I get a response that says "Sorry, I don't know what to do with: "url-to-card-or-board". Try one of these instead?"

It seems like the documentation is out of date, and/or this feature has been discontinued. Anyone know what's up with that?

Interesting, they must have done away with all the ability to show private content at all. There must have been some issue with people in the slack who were not in the trello board and accidentally sharing things they shouldn't have

Nope. It says "For security reasons, you can't preview private content in Slack channels."

@Stephanie Bryant i would say there's a super strong likelihood the docs are out of date. when you do `/trello logout` and then `/trello login` does it work to just naturally unfurl the links?
