Google map can not be moved or zoom in/out

Hello, make an application with a modal for google maps, the map is displayed correctly but I can not for example move or zoom in/out in it. While I enable those options, I am not allowed such actions.
In the css I have:
ion-app.gmaps_cdv .ion-page:not(.gmaps_cdv), ion-app.gmaps_cdv ion-modal:not(.gmaps_cdv) { display: none; }
Any help me?
Thanks and regards
