3.0 Can't update audio on website

Can't say it much more clearly than that. I reported this to the website forum two days ago and have not even received an acknowledgement. I made a change to my score, "upload to web", and the sound is not changed, although the score is. If I cannot update my scores by any means except creating a new page, my incentive to use 3.0 is correspondingly reduced. Others have reported the same problem. I'm not even sure it's 3.0 specific.
