Hi,
A few days back my account has been added to other companys iTunes Connect. Since then I am unable to log in using the Application Loader. I've already reset my password and confirm that I can login using the appleid.apple.com or xcode (Preferences->Accounts). My account does not use the two step verification process. Now I am unable to upload any ipa file built outside of xcode. Could you please advise on the matter?
