Here’s something I’ve been doing and I like how it looks on my captions.
Instead of adding captions with (–) to make paragraphs, do it with (⠀⠀⠀⠀⠀⠀⠀⠀⠀).
This exact amount of “spaces” between lines, will give you a post that looks just like the post I made here on MP (with blank spaces between the lines), and not something like the following example.
“Hello
(------)
Etc
(------)
Etc
(------)
Hashtags”
But something like this:
“Hello
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Etc
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Etc
⠀⠀⠀⠀⠀⠀⠀⠀⠀
Hashtags”
Hope this works for you.
