I've enjoyed using Artemis even though I can't login through it (I'm on kbin). It's been interesting to be a pure lurker instead of an avid commenter like I was on the former site. In the past couple of days, though, Artemis has failed to fetch any new content. Deleting the iOS app and reinstalling through Testflight does nothing; the 1-2 day old posts pop right back up and nothing new will come in.
At this point the question has to be asked: is work on Artemis still proceeding? Aside from a few drips and drabs Hariette hasn't been heard from in at least a month. I really hope the dream of an Apollo-like fediverse app -- which Artemis was already previewing very well for us -- isn't dead.
