NSFW posts not displaying

I have my Lemmy profile set to show NSFW posts (blurred), and the same configuration in Connect.

However, I've just realised that NSFW posts aren't showing up at all. I'm not sure how long this has been broken for, as I don't get many in my feed - I just happened to know there was a NSFW post in a community, which I couldn't see when I went to look for it in Connect.
