In advance, sorry for my broken English.
I have been having a speed issue on Zwift for some time with my Tacx Flux.
The speed is unrealistic, I can do flat courses by doing 18/20kms per hour when before at the same time I was doing a classic distance +/- 30kms.
I tried logging in on my iPad, then on a MacBook Air, no change. Also I disabled the rest of the devices in Bluetooth.
Do you have a solution ? I thought of an Ant+ key but this would itself be connected via an intermediate cable, my devices not having USB ports.
Thanks for your help, have a nice day!
