Hello, I cannot seem to get my zwift dialed in with tacx vortex. I am calibrated correctly but my cadance is really high and watts very low when there is any hill and I drop to almost 0 mph. I have tried everything I know. Connected to an ipad pro, and also listen to music from same device. Eveything is Bluetooth connected and I dont use a seperate cadance monitor. Please advise as it is very frustrating riding hard but not moving! 
Hey Anthony, has this only been happening recently or have you had these wattage and cadence issues for a while?
