Hello.
I have more than one device which has enable location service / tracking (location registration), so I can see on Google Maps where my units is located.All is using my default @gmail.com account


Earlier I through the "Timeline" could choose one of my devices, and date and then see how the selected device has found itself in during the day. When I go into the Timeline now, I can only see one of my units, and I do not have the opportunity to choose between them I have. How do I choose a device for subsequently acquiring certain timeline for the choose device?
