Below is the message I got from Deniel
Hi,
I have seen a few times that my workouts doe not upload to Strava… Sometimes it takes a day or two, but really lack the possibility to see that Status of Strava uploads on my Workouts. Right now I have a workout that I did yesterday that has not yet been uploaded.
Regards and thanks for a fantastic app! Keep up the good work
Regards
Deniel
