Hi there - I have found on multiple occasions that the resistance goes really low (approx 80W) on my Tacx Flux 2 - this happens sometime at the start of a ride or if I pause at other times. Have rebooted, re-calibrated, changed from Android Phone to Apple Phone, and turned off all other devices (eg Garmin 520). It still happening, very frustrating when I want to do a session - would appreciated help - need to go to older version of Firmware? Currently 3.3.45 / 1.1.6
