I uploaded a few new commute activities today; three of them appeared to not upload correctly as the upload spinner didn't go away. The activities were processed correctly by RideWithGPS and by MyTourBook, so I was fairly sure they were OK, but it appeared that Connect had trouble processing them.
The odd thing is that they *were* uploaded correctly, so I'm not sure why the Connect upload page didn't indicate that, but rather that they were still processing.
The activities in question, if anyone from Garmin ever decides to look at this forum (are the pigs flying yet?), are:
