I just came here with the same/similar issue. I made a post yesterday but can’t find it anywhere except my, like, comments inbox (whatever it is called, the list of comments on my posts). I am using the Liftoff and Jerboa apps. My account is .world and the instance I posted in is .ml, maybe that has something to do with it? (I don’t actually understand any of this and it is a near miracle that I am here at all)
