My App was rejected by Apple, Now I have fixed the issues and want to upload the updated bundle file, but when I try opening the compressed bundle file using Application loa
You need to click on the "Ready to Submit Binary" button in iTunes Connect first before doing this.
Click on your app - you'll find the button on the top right.
try it in Safari. I was struggling with this in Chrome.
You need to login in to iTunes connects and need to do again "Ready to submit binary". Right now your app status should be "Rejected". So you must do that first before uploading through Application loader.
