All my app screenshots and icon disappeared when I created a new version

I was preparing a new update for our app, as usual, but in the new version all the assets automatically disappeared (screenshots, app icon, etc.), and I have no option to bring them back automatically, except by re-uploading each and every one of them manually for each localization?


This isn't acceptable, we can't be asked to reupload all our assets for every update...
