Well stil not ok. I succeed to launch Zwift on my IPad but the speed and the cadence measurement were very strange. i noticed after my session that my 2 sensors (cadence and speed) were crossed : Zwift read the speed instead of the cadence and vice versa…
I tried several times to unpaired and paired again the sensor : I can’t do anything.
I have only the possibility to change the size of the wheel. Zwift decide alone which sensor to use. 
It is about one month that Zwift is unavailable on IOS. But I’m still paying the bill…
Up.
As usual no answer from Zwift
