I'm submitting a new version of my app, and after click "submit for Review", it show that: A few more items are needed in order to submit for review The items listed below are required for submission:There are still screenshot uploads in progress. I didn't met this problem before. Is that mean I haven't upload all the screenshot required or it's still uploading the screenshots to App Store Connect's server? Cause before there is a "save" button after you drag images to the screenshots area, now you don't. And I think I have uploaded all the screenshots needed and I waited a day to try submit again, still the same. What should I do?
