I use a Garmin Express on a PC to upload my 910Xt activities to my account.
I also use the same Garmin Express on the same PC to upload my friend's 910Xt activities to her account.
It used to work fine. However, since 2-3 weeks, I have not been able to upload my activities anymore into my Garmin Connect page, although I can still upload my friend's activities in her Garmin Connect page.
It seems that my activities are transferred correctly from my 910xt device to Garmin Express, but they then remain blocked into Garmin Express (I suspect that because the transfer is displayed as usual on my 910xt ; then Garmin Express asks my credentials ; I enter them but afterwards, Garmin Express does not indicate whether it is ok or not, and my activities never appear in Garmin Connect).
I've updated Garmin Express to 4.0.19.0 but it does not help.
If a use another PC for uploading my activities, it solves the problem, but I don't want to do it each time I need to upload activities.
