Hi,

Please try add more this code to Customize > Custom CSS to fixed it:

\
@media only screen and (max-width: 479px){\
a img.alignleft {\
    margin: 5px 30px 22px 0;\
    float: left;\
}\
a img.alignright {\
 margin: 5px 0 22px 30px;\
    float: right;\
}\
}

Or use this code to make the text wrapping around drop to new lines on mobile:

\
@media only screen and (max-width: 479px){\
a img.alignleft, a img.alignright, a img.alignnone {\
    margin: 0 auto 30px auto;\
    float: none;\
    display: block;\
}\
}\

Best Regards,
