I have experienced many drop outs recently with my Stages cranks. The firmware is up to date and it works fine with Trainerroad, Bkool and Garmin. Also it seems to have the started after one of the recent updates. I am using an antenna to connect but now it seems to only connect after I put resistance on rather than just spinning the crank backwards. Also, the drop out sometimes happen when I simply soft pedal or drop my cadence or when I increase my watts dramatically.
I can send the log files from today 3/10.
