How do I keep a post's caption always visible?

Even with paid posts, you can have the caption always visible to everyone (unlike the content itself):

  1. write a caption when creating a post and attach media;
  2. click / tap Next;
  3. activate Keep Caption Always Visible;

  4. click / tap Create Post;

⚠️ There is no Keep Caption Always Visible option for "Teaser Posts", because they are by default visible to everyone.
