Enhanced iTunes Summary – shortcodes?

Question about the enhanced itunes summary check box option…

How does this work w/ shortcodes? Or from Shortcodes from builder themes like Divi?

Does it strip out short codes in general?

Is there a way that I can run a test; see what happens before checking the box?

The screenshots on this tutorial demonstrate what it does with text formatting, but not what it does with shortcodes, images, youtube embeds and more. Also is there a text limit or a count at which it stops or does it work through an entire Post?

This is more of a presale question, looking at migrating from one hosting company to Blubrry hosting (already running the plugin)… Feel the need to get things consistent. ??
