Doesn’t work – Treadmill Smart Speed - Designed for Zwift Runs Review

I loaded the app on my iPhone 11 but it won’t enter the speed on Zwift. I was really looking forward to this as a solution but no matter what speed you set it to the reading on Zwift is 0.0. No real troubleshooting information either.
