I faced the same issue and waited for Apple support... seems they are really busy these days in Covid times. Now I solved it myself after reading the helpful articles here - thank you guys! 👍🏻 How I solved the issue: This time I used Google Chrome Deleted all screenshots Refreshed the AppStore (browser) Checked all screenshots again and I found some 'lost' screenshots - and deleted them Uploaded the screenshots, one by one in the exact order I wanted to have them (before I've changed the order after uploading the screenshots in the AppStore. This time I didn't touch any screenshot after uploading again) 6. Submitted and it worked finally. Good luck! Stay safe and keep well!
