Hmm... Are you sure you’re listed as a member and not just a watcher? Another deviant brought up an issue with people being unable to join recently so that might be the problem—it could be listed as watching, which is why it shows up in your notifications, instead of being a member. If that’s the case, I think I fixed the bug to join the group so you can try re-joining? Or you could PM me a screen shot of what you see when you’re looking at the group page and I can try to help you from there.
