problem

Hi @giuliapep
This would be about the tooltip size on mobile, correct?
Did you try the css recommended here?
https://interactivegeomaps.com/docs/tooltip-styling-with-custom-css/
(last example).

You can also try this combination

@media only screen and (max-width:780px) {
.map_wrapper .imapsLabel {
    font-size:0.8em;
    line-height:1em;	
}
.map_wrapper .imapsLabel img {
   max-width:100px;
margin-bottom:5px;
}

.map_wrapper foreignObject div {
	max-width:150px !important;
	white-space:normal !important;
}
}
