I am using a brand new Bowflex treadmill with Bluetooth output, connects fine to zwift via ipad. Often when I begin a run, there is no speed coming through to zwift even though the treadmill is running. I have to relaunch the app to solve the issue which works 9 times out to 10. I also have a heart rate monitor and zwift foot pod connect to the zwift via iPad at the same time. Can anyone help?
