Hi - I have the TACX Vortex Smart Trainer and having a very difficult time getting the resistance to work. I used this trainer with Zwift 4 months ago successfully and haven’t been back on for a while and now getting no resistance. I am connecting to the “Controller Smart Trainer” option and successfully able to pair to the device. I have searched these forums and tried a lot of different things, but nothing seems to be working. I did see where one post that indicated the trainer had to be at 3.1.7. (I am at 3.1.2 and it worked last time so not sure this is the problem), but also when using the TACX Utility App from my iPhone, it isnt giving me an option to upgrade past my current version.
Any help or suggestions would be much appreciated.
