You are not authorised to use this service iTunes app upload error [closed]
Solution 1:
I had the same issue today. What I did is mentioned below.
Go to XCode -> Preferences -> Accounts -> Apple Ids
From that select your Apple ID, remove it, and then add it again. Quit Xcode, open it again, and then clean and archive the project.
It worked for me.
Hope it works for someone else also.
EDIT
If your Apple ID is already there you can also try with refresh button for all provisioning profiles and certificates.
Then restart Xcode, clean and build the project. You'll be good to go!
Solution 2:
On Xcode 7.1 I disabled bitcode during the submission and it uploaded perfectly.
EDIT: You can also export your app archive (iOS App Store Submission) and use Application Loader (press choose button and locate your export file). There is no "Include bitcode" option, so my Guess is it's off by default in Application Loader.
