Not for the first time and surely not the last… I did a cycle recorded on my Edge 810 and tried to upload via iPhone Connect app and got the upload failed message. Tried the usual reboot of the Garmin, reboot of the phone, disconnect and reconnect and still nothing. Recorded a 10 second activity and it uploads fine. The actual activity I want appears ok on the Garmin - I.e. not corrupted.
This is a regular occurrence and to fix I’ve had to connect to a laptop and upload manually but I am abroad on a training camp with no laptop with me.
Very frustrating!! Anyone had this issue / found a fix?
