Hi,
Started riding indoor (Tacx Flux S form 2021) after my summer break and noticed that there is no need anymore to shift to smaller gears when uphill, i can just ride same gear all he time? (same power output, just lower speeds..)
When did this changes happen? Did i miss an update? Because this reminds me to a kind of ERG mode which i don’t like..
Cheers,
Joris
Something is wrong there.
Do you definitely have the Resistance device paired? How are you pairing, Bluetooth? What device do you run Zwift on, e.g. laptop?
bleutooth pairing on ipad
Check the trainer difficulty setting in Zwift. If it is set to 0% you would see the behavior you described. Set the slider to something higher than 0% to feel changes in incline in sim mode
On the pairing screen, is the Resistance tile blue? (If the trainer isn’t paired for Resistance you also won’t find the Trainer Difficulty setting that Magnus mentioned.)
Any chance the trainer is being controlled by something else like the Tacx app still running and paired to the trainer, or a second copy of Zwift somewhere else?
Thanks for the feedback, resistance tile was not blue indeed - used to switch iPad sometimes, maybe it was synchroon with the other one last time. Pairing and resistance now okay - tester it on the grade 
It’s unsafe to run Zwift on more than one device so if you’re able to pick one and delete the app from all others, that is the best way.
