BUG: “you do not have permission to access this content” on my own post

I was replying to something and noticed one of my feed posts had no shown engagement though the ones above and below it are normal (and about the same show). I also saw that if I tap the heart, it goes from 0 to17 though no icons appear there. When I tried testing the share link, I get my feed tab but with no post there and this warning:

The post link: https://mydramalist.com/profile/elbee/feeds/19nAgmio

Edit: I asked in a friends-only feed post, and none of the ones who replied could see it, either. It can be viewed by me scrolling down my feeds but is not visible from a direct share link.  I reposted the contents in a working post, but figuring out what broke would be useful so less breaks in the same way.
