Hi @brunocloutier
Plese keep in mind that Google Map field will set the map center to Melbourne if you didn’t set the Center option on the field editor page. If you need to use Google Map geolocation feature, you can try to modify the map arguments or use Javascript to modify the map. This page should give you more idea about it: https://www.advancedcustomfields.com/resources/adding-custom-javascript-fields/.
I hope this helps 🙂
