I always check in at the 24 hour mark. Once I check in, I can do SDC either by phone or at the check-in page (by checking in again) or at the reservation page (click on change flights). I did this twice recently with no issues. Not sure why you would have to cancel check-in with SDC (never had to cancel it before -- just re-checkin).
