I'm trying to upload screenshots of my app to publish my app but an error keeps preventing me to do so. I've successfully uploaded screenshots for 6.5" display, when doing the same thing for 5.5" display, I drag the image, the progress bar appears and goes away and the image is uploaded. After a few seconds, the screenshot turns red with error "Somthing went wrong. Delete the assets and try again".
Well, I've tried multiple times with different images but getting the same error. Any ideas?
