It is showing up.
When you say not showing up — what does that even mean? Which specific casts are not showing up? Home feeds are sorted on each request and its up to the viewer and their interest in cast authors. Just because when they fetch the feed the cast did not show up, does not mean its forever omitted. What is likely that it would have probably showed up if they scrolled down or pulled-to-refresh.
I understand that you are experiencing possibly different engagement counts on some of your casts and I want to further investigate and fully uncover what might be going on. But I can state now that its not because it has a video attachment. Feel free to DM me specific casts.
