Hi I am using Ultegra R8000 Dual sided PM, I got it last year in August, in October Stages replaced the left crank arm because of calibration issues. On Saturday I found that only my right side recorded data, went home, replaced batteries, updated the firmware to version 1.6.8. On Sunday's ride it was only picking up left, and power was a lot lower than what it should have been, as after 60km my NP was only 100 Watts. I deleted my PM from my Garmin, when I tried to add it again my ANT+ code was completely wrong. And didn't connect to my Stages at all after that. Has anyone ever experienced something like this? I would love to UPGRADE to something more reliable, but unfortunately with the current Economic challenges it's a bit of an expensive thing to do. So would like to get what I am using working again for time being? Any advice would be appreciated.
