The image seems to be…invalid? I’m not sure why, but it shows up as a 0 x 0px image in Designer here. Could it be a iffy upload & mobile has an old cache?
I might try either re-selecting the image or re-uploading it.
I chose another image and it seemed to display (note the hard-coded image height/width under image settings, which is not responsive. Meaning to say, it will be 648px across all breakpoints. I believe most people set the image size via its CSS which is responsive (on the first tab), not on the image settings itself. Responsive here = changeable across breakpoints.
