Image captions for Gallery Block / Image Block on Mobile

Hi! I need some help with Image Blocks / grid Gallery Blocks on mobile.

Right now I've got captions added to my images, and each image is set to open in lightbox. When tapping the image, it opens up in lightbox without issue, however, the only way to see the caption is by tapping the tiny little white dot at the bottom right of the mobile display. This is confusing. I'd like to have the caption appear automatically when tapped on mobile.

Can someone help me out with this? I'm stuck and could use some help! :)
