this is not a bug, but it’s how it currently works. When using Lightbox, it will always take the desktop source as the Lightbox image.
You can create multiple image elements, one for desktop and one for mobile, and then it will show correctly.
Thanks Matej for your reply. I understand what you mean and actually your solution is what I did right after sending the report.
But did you check the video? In it you can see that both images are displayed at first, and then the secondary one disappears. It looks like a bug.
I guess in this case, if using the desktop image on the lightbox is what we want, the problem is the zoom-in animation when opening the image, and the solution would be to change it fo “fade” or “none”.
