Hi there! Looks like you linked to a Lemmy community using a URL instead of its name, which doesn't work well for people on different instances. Try fixing it like this: !shrinkflation@lemmy.ca
On that note, I'm kind of annoyed that the Threadiverse doesn't have a standard way to link to a post or comment in a cross-instance way, just to a community.
Navigating instances should have been made more seamless. I think Mastodon handles it better by asking for your home instance before doing an action, so it doesn't matter what instance you actually come from, but it's still imperfect.
