When I'm not using the device, the app keeps nagging me with a ""Connect to your TomTom device" notification (which also keeps giving me vibrating notifications on my smart watch - really irritating). I only want to connect to the satnav when I'm using it - most of the time it's turned off so I couldn't connect if I wanted to. How do I tell it I only want to connect when I'm using it? (I know I could turn off *all* notifications. but I do want notifications available when I'm actually using it).
