Pixelated and blurred images on your demo (mobile version)
I attached two screenshots. The logos and photos are OK in desktop version, but in mobile (iPhone 7) the images are totally pixelated. I don't know why. It's normal with your theme? It happens in all the demos I've checked.
Could you say if I buy the theme, it will happen? I love your theme and posibilites... and It's very bad cause it seems a problem of you.
