I tried to connect my today arrived Mi Band 3, yet it does not work. I can not connect to my location or any other when asked to log in and connect to a location.

I tried de-installing and reinstalling.Restarting the phone.
Different accounts. Google Mail, my persona mail and a yahoo mail with a .com adress.
Enabiling access to location in app settings and extra permissions.

I am using an android device Samsung galaxy a6+.

Why does it not work? I really want to test the new device.
