For the first one, have you tried setting/updating the post styles to indicate post height? Docs here, example code here:

await reddit.submitCustomPost({
 "title": "Post with styles title",
  "styles": {
    "height": "TALL", // <-- This is the important bit
  }
})

Best guess I've got is that you moderate a lot of subreddits, and there might be an issue in our UI that we don't show all of them if there's a lot. I'd recommend using the CLI in your case specifically - it'd be faster anyways, since you won't have to scroll through a list of subs, you can just type it out.
