If you are looking to edit a .FIT file, for various reasons, then upload it to powercenter we suggest using the program below...
Once you have downloaded your edited .Fit file, you can manually upload it to PowerCenter by going to the "Settings" tab and scrolling down to the "Upload Window"
If PowerCEnter says that the file was uploaded, but you are not seeing the Edited activity in your Calendar...it may be that you have the original file still in the calendar. PowerCenter recognizes this as a repeated upload and will not duplicate the activity.
All you have to do is delete the original activity and upload the edited activity.
If you have more questions or concerns, please reach out to email@example.com
