A Hide on mobile option would be really nice
Happy to see you with us! Welcome 
I agree that it would be great such an option right in the configurator. We’ll try to consider this idea in our future updates.
As for now, you can use this CSS code to hide widget on mobile devices:
@media (max-width: 450px) {
.elfsight-app-WIDGET_ID {
display: none !important;
}
}
Here you need to replace WIDGET_ID with the ID of your widget and add the code to the Custom CSS section on the Style tab of your widget settings.
