If it’s set at miles it will show miles when your signed in, but you need to refresh when you go in again and sign in. I use biometric sign it and it then changes to miles again .

I just set the ohme one to full charge always and then use the blue link to set what I want. Usually 90% charge.
This then give me if I wish to block the charging by going into ohme one and pressing pause, so no one can use it if I’m away.
