So to recap, my problem is not getting Alexa to work, but keeping it working from the sense. Whenever I actually want to use it it says I have to complete the setup on the phone, so totally pointless. I suspect it is when the phone and watch are out of range of each other, it obviously then loses contact, but it should reestablish that automatically when in range again and it doesn't seem to. The obvious way it should work is that if it cannot see your phone it says so, and as soon as you are within range again then it should automatically start working again. It doesn't seem to do that. This is pretty much a no brainer bit of functionality and I cannot believe this was not tested. Unfortunately it means the alexa functionality is really not fit for purpose as it stands.
