I'm a user on Lemmy and I posted the direct link in the Vancouver community here. Something seems to have changed with how Mastodon displays threadiverse content, since this is the second time someone has complained about it from mastodon in the past week. I'm not sure what I can do to help with the formatting from my side.
For what it's worth, you should be able to see all the content without logging in to Lemmy, or any other threadiverse platform for that matter
