My Tacx Vortex with the latest firmware is only detected as a power meter and cadence sensor, not a controllable trainer. I’m using Bluetooth through the Zwift Mobile Link on Android. I see that something similar was a known issue almost three months ago (https://support.zwift.com/hc/en-us/articles/213614686-Some-BLE-Smart-Trainers-can-t-pair-as-Power-and-Controllable-Trainer?section=201540443), but I would think that it would have been fixed by now. Is it not?
If this is the same issue, are there any workarounds besides using ANT+ (which won’t work for my setup)?
