Hello!  
I have used my Garmin vector 2S with TrainerRoad/Zwift on my PC with an ANT+ antenna. I use a Tacx Flux trainer. On my last session, there was a problem with the power meter showing huge numbers (250-500w with normal pedalling), so I tried an unsuccessfull calibration. I saw that the power meter wasn’t blinking, I then changed the battery - all good. I did a successfull calibration. When the session started though, I was producing 0 watts. The cadence was working, so the session started, but there was ZERO watts… Whats wrong? 😭

Need to set vector angles and calibrate with Garmin head unit. Then all works. Happened to me tonight! 😂
