@tuanphan I am having a similar issue with my banner getting cut off on mobile as well. I'm not necessarily expecting to get the same ratios as on the desktop, but I'd at least like more of it showing. I've tried inserting codes and putting the block id for the banner in there, but I must be doing something wrong because it has no effect on it.
