I really feel like I'm missing something here, as I can see that on the Editor X Breakpoint Tutorial 1 they show the image of the fan changing image file on the mobile breakpoint (it goes from a side-on shot to a front-on shot).
I went to do this on my site and can't seem to get it to work. Dropped down to the mobile breakpoint, changed the image, and it affected the desktop and tablet image file too.
I thought it could be as I was doing it on a stretched hero section, but when testing it with other placements it always changes the file for all 3 breakpoints.
Am I missing something here? Is this a bug? I definitely got this to work at some point before.
