Beginning on approximately Spetember 13th, workout notes were not getting saved. The bug causing this problem was fixed at approximately 7:35 PM CDT on the evening of September 17th. I'm terribly sorry for any inconvenience this may have caused. You should now be able to add notes to new workouts or modify workouts to add notes as would be expected.
If you experience any other problems, please don't hesitate to let me know.
