I have downloaded Ather Grid App, however I do not see Ather vehicle in the scroll down. Why?

The reason why Ather vehicles are not on the list is that they will not need the app, as all vehicles have direct authentication and will start to charge as soon as connected to the charging Point.

You may select any other vehicle from the list on the app to view the locations. As for Ather owners, the locations are directly available on the dashboard and on the Ather App
