iTunes Connect uploading issue

Too bad that iTunes Connect changed its behavior recently. I'm providing an update to an existing app. I submitted new binary using the Loader without problem on the first try. Then I discovered that different from before, one has to reject the binaries in order to change screenshots.

Too bad that the update is in the status of "In Review". Well, I have to rejected my binaries and begin to upload new screenshots, because I don't want to display screenshots of previous version. The new screen shots are uploaded but I'm stuck in "Developer rejected" status. Meaning I cannot upload the binaries and not able to change screenshots from th开发者_JS百科at time on. The following error will appear when click Save Changes in either situations.

"There was an error saving changes. Please try again later or contact iTunes Connect Support at itunesconnect@apple.com."

I checked the source of the error page and think it's this error

id="lcBoxWrapperHeaderTextUpdaterContainer"    
action="/WebObjects/iTunesConnect.woa/wo/7.0.0.9.7.7.1.1.1.1" errorId="ajaxContainerError"

I have reported iTune Connect via the "Contact us" link on this issue but not get any response back for 2 days already. Very disappointing.

Did anybody experience similar issue? How did you resolve this?
