I accept any comments.
Thanks
I'm also experiencing the same issues as above. On Edge 520, I'm just seeing the blue IQ logo with yellow exclamation circle. This had worked for some time with no problem! But I'm not exactly sure what might have changed that I'm now receiving this error, if it was a firmware update to 520 or something else. I have inputted a threshold HR through Garmin Express, but still does not seem to work. May I email you the log file? Thanks!!
