Me using Classic Themes and PS 184.108.40.206
I am not able to get Banner module img displayed on mobile devices, please try out the following:
1) Install and configure "Banner" native module for PS;
2) Enable mobile;
3) Check out on any mobile device (me tried on Android);
Result: Banner img is not being displayed on mobile devices.
Expected results: a banner img should be desplayed on mobile devices once enabled.
PS: It seem a CSS issue > "hidden-sm-down" not being removed from HTML
