Update:
I tried to load results dynamically using the “Displaying content” > “Show more” option on each individual gallery, but in that case I encounter a weird bug.
Assume a gallery has rows of four elements, so I set the options “videos per page” to 4. Then, when accessing the gallery, it correctly displays the “Show more” button and when clicked, it loads some content.
The problem comes on how this content is loaded. It only loads the first video of the second page (on a gallery containing 8 videos), and it displays it on top of the first video. I assume the normal behaviour would be to append the 4 new videos in a new row under the first one.
Is this a documented bug or maybe a conflict with my template?
