I figured out one bug detail… as soon as you make any edit, even just fixing typos, the post disappears. (Edit: disappears and won’t let you check the box to make it show again no matter how many tries, well, at least up to 25 or so across the last day!)
This post is one I tested it with after one was showing, had some typos/autocorrect mishaps changed and more added in the process, and disappeared as soon as it was edited.

The process, screenshots as I went along:






Hopefully that helps at least get one bit of coding resolved!
