I have the Tacx Vortex smart trainer and I’m using an iPhone XR with the Tacx Utility App to setup my trainer. To the best of my knowledge, my tire is inflated correctly and the bike and trainer are setup correctly. The iPhone and Tacx Utility app recognize the Vortex via Bluetooth but when attempting to calibrate and I’m prompted to start pedaling, there is no output displayed on the app screen. It just simply states “start pedaling” and nothing else shows. I tried several things for quite a while last night with no success.
