Hello,
Especially after I updated my Edge 840 to the latest version - 18.17, it's almost impossible to train. I'm losing all the time the connection with my Flux 2 trainer, HR and cadence sensor.
I was having the same issues with the 9,29 version, but way less, and I was still able to finish my workout. Today, I lost completely the connection with my trainer and I abandoned the workout..
I hope you can fix this issue, it's not funny at all.
Best regards,
