Hello,
Sorry for the delay. Add the following code in Theme Options > Styling > Custom CSS
@media only screen and (max-width: 480px){
.woocommerce-account .woocommerce .u-columns {
-webkit-box-orient: vertical;
-webkit-box-direction: normal;
-webkit-flex-direction: column;
-ms-flex-direction: column;
flex-direction: column;
}
.woocommerce-account .woocommerce .u-columns .u-column2{
padding-left: 0;
}
}
This issue was fixed in version 3.13 of our theme.
Regards
