Tacx Flux S calibration issues

Tacx Flux S, purchased in May 2021. It does not auto calibrate in  ERG mode resistance does not auto pick the load of the workout and I have to manually change the gears. The software has been updated, have tried to calibrate in various app (Zwift, Training peaks and Tacx app) but still does not pick the workout as per desired and set. This has been an issues since very long and it has not been resolved.
