When trying to share a group via a user's news feed by entering the URL, the link in the post works, but the page preview is just a broken image. Is there another way to share a group to a user's post?
I have a ticket open there as well.
There is no option in standard OSSN version to preview what is shared, if you are talking about softlab24 product then you should contact there.
Due to the many requests in the past for additonal features and components we have decided to develope a premium version. Features like Hashtags, Videos, Polls, Events, Stories, Link Preview, etc included in it.
