Running speed always zero that was transmited from another Android threadmill transmitter

hi,

I want to report a issue about speed value always show zero on Android Zwift.

I have a garmin watch and want to connect this watch to Android Zwift by Threadmill Speed transmitter

Follow this video, I can start running on iphone’s zwift finally.
For Android version, Zwift can also find the threadmill transmitter “ASUS_Z01RD 124” with bluetooth, but the only problem is speed value always ZERO.
ex:


Hope zwift team can help to find out the root cause and fix it soon.
Thanks!!
