@mmetcalfe No, you are not doing it wrong. I can't figure out why your posts didn't get marked in our experimental filtering system, because they both include the prompt word. Thanks for the heads up. Maybe Manton will be able to figure it out. Meanwhile, we add yours manually. Sorry for the oversight.
@jean Hi Jean - If it helps: I initially did the posts in Sunlight, and I can't really get to grips with Sunlight, TBH. The alt text never seems to stick, and I can't find a way to add a short line of text - just a post title - so I fix the posts in the MB web client - editing them to add the alt text and whatever thoughts the scene triggered my sieve-like mind has retained. So maybe the photo upload is missed then subsequently ignored when I fix?
@mmetcalfe Unfortunately the alt text problem in Sunlit is a known bug. We have the fix ready but it hasn't been submitted to Apple for review yet. Will do this very soon.
