Map Layout

My app’s URL: https://facilit-e.glideapp.io/

Fo some reason, some of my addresses in Paris are not located properly on the map. Even though I have tested them in google maps. They appear in different location in France, Canada and even Japan.
Is there a format to be used so that it is accurate all the time ?

The best format is Lat, Lng (GPS coordinates of the location).

Where can I find the GPS coordinates of a location in Google. (Sorry, real blonde building an app :joy:)

An example: Go to this link: https://goo.gl/maps/QSobPWzTjdTGQ2uQ9
This is the White House.

Go to the URL in your browser: https://www.google.com/maps/place/The+White+House/@38.8976805,-77.0387185,17z/data=!3m1!4b1!4m5!3m4!1s0x89b7b7bcdecbb1df:0x715969d86d0b76bf!8m2!3d38.8976763!4d-77.0365298

This number pair (38.8976805,-77.0387185) in the URL after ‘@’ is the GPS location (Lat, Lng).

Many thanks for the tip.
