Hi there,
Thank you so much for getting in touch, we really appreciate your time.
You should be able to make use of some custom JavaScript to adjust this text.
Could I kindly ask you to navigate to -> Maps -> Settings -> Advanced -> Kindly copy the below custom JavaScript and paste it into the custom Js field.
jQuery(document).load(function(){
jQuery(“#wpgmza_ugm_addmarker”).prop(‘value’, ‘New Text Here’);
})
Once complete, click save and confirm?
Please let me know if this helps?
Kindest Regards,
Steven De Beer
