I was checking out the file download capability from the activities list on the dashboard and found that the filenames generated are only based on date. (ie: zwift_01_09_2015.fit ) The filenames generated by the app contain the date and allow for multiple rides per day without the need to modify the filename (ie: K.Litterer_2015-01-09-18-25-13.fit). I also have a scenario on my activity list where the downloaded filename does not match the date on the activity list. My activity “Zwift - 01/03/2015 Island” generates the file zwift_01_04_2015.fit. The data in it is correct other than that.
