I am getting two errors on submit: • There are still screenshot uploads in progress. • There was an unexpected error with your preview. I've checked all my screenshots and preview in the Media Manager and all of them are visible (no grey images) so everything seems fine. What can be the reason and how to fix this? I strongly prefer not to delete all screenshots and start over from the beginning because uploading them seems to be a very big problem with the new AppStore connect site. It constantly fails, freezes and takes hours just for one language. I am wondering why is so hard to upload a bunch of images.
