My treadmill not showing up on my lily watch, I have synced several times with my phone but nothing - it is a brand new lily.
It is the 3.20 version
Also, the App just released an update, can you be sure the app is up to date.
I am having the same problem and as far as I am aware, the watch is up to date as I just accepted an update before I began to use the watch
OK, lets reset the device, remove the pairing and add it back! Then add the treadmill activity from the app and sync the device.
