Do Custom Programs Update Automatically

[1stCoachJoe]

I created a custom program, which I've since modified. When tracking my workouts from the program via the calendar link, I noticed that the changes I had made were not updated. Does it take a few days for the servers to make the updates, or does one need to remove the old program from the calendar and then reinstall the same modified program back into the calendar in order to get the latest updates reflected? thx!
