This is the issue. You need to log in, and join the server in order to access this information. Idk if it is still true, but there was a limit to the number of people who could join these communities. Which further complicates access to this information.
Doesn’t Lemmy also do this? On the few accounts I have across instances I’ve had to explicitly check the “Show NSFW” box when I create my account.
