Until today I was using Garmin Express 7.12.1.0 on a PC to upload activities from my Forerunner 630 and this worked fine, leaving the activity files on the watch for me to view there and/or copy elsewhere as I chose. Today the program updated to V7.13, and I found that after (successful) upload of a new activity, all activities were deleted from the watch (including any uploaded previously). I can find no release notes for this version so I am unable to determine whether the change was deliberate or not, but if it was, then what is the justification, please? Garmin devices always delete (or overwrite) the oldest activities when their storage is full, so wiping activities on upload seems to me utterly pointless and undesirable; at the very least, there should be an option to override it.
