Trainer Road on ant+ help, thoughts?

I am able to use TR on my Android phone set in airplane mode w/ wifi on, Great – But – with my windows pc using Bluetooth for Zwift, using a power meter and dumb trainer –

After the workout my stages power meter even after calibrated is significantly off; I know this because I hard re-boot the power meter and my HR is back in line with power output.

Anyone have this issue &/or suggestions?

Also, I’ve seen a TR kit on Zwift and wonder who the group is and how they make it work – thoughts?

Thanks for the consideration
