I've installed the plugin and am testing it on my laptop. No arrow icons to browse to the next/prev images in a gallery. Keyboard keys not working either so I'm stuck on the same images. Any idea why?

Also it doesn't display captions/descriptions/alt texts as captions. As this aspect isn't covered in the video I was wondering if it's on purpose or if there's something extra to do in order to display captions.

Thanks!
