I have submitted my app on the App Store. It is still waiting for review. I got mail:
Your iOS Distribution certificate has been revoked.
Dea
If you delete/ generate new certificate in Provisioning Portal(Certificates) then you get these types of messages "Your Development Certificate Has Been Revoked - you have revoked your Development certificate and it' s no longer valid".
To overcome this you need to generate provisioning profiles with the newly created distribution certificate, sign the build using the same, recreate the build and resubmit the app for review to AppStore.
