Question

I am trying to update my application , but after uploading the binary , Itunes connect sends me this email :

Dear Developer, Thank you for your recent

I had the same message appear from Apple, and selecting "targets" not "projects" when setting code signing identity did NOT resolve my issue.

Turns out, as the last step of submitting the app to the store (via XCode4's Organizer panel - Archives tab), I was presented with a dialog sheet that showed the distribution certificate it was going to be submitted with, which was DEFAULTING TO A DIFFERENT DISTRIBUTION CERTIFICATE I had in my keychain - and NOT the valid certificate that I'd signed the app with!

Once I manually selected the correct distribution certificate in this last step of app submission, it went through fine. (I also opened up my Keychain Access app and deleted the offending distribution profile, that I didn't have any use for anymore).
