@sindarina Yeah, I've puzzled over this for days, tried a couple things, and no luck. It's not a big deal — it involves about 4 posts/day — but it's frustrating that I can't figure out why it's not working.
As far as I can tell from what you've written, you've done this correctly so I'm not sure why it wouldn't be working for you.
I did notice that I had to refresh the post to make the filter kick in. Are you seeing this unfiltered even after refreshing your view of the timeline?
@feditips@sindarina Thanks for checking! Oddly enough, it just started working overnight, after days of *not* working. I didn't change anything in my settings, either. So who knows?
