Submitting app started by other developer

Question

I am trying to submit an app started by another dev, he created all the certificates and provisioning profiles, and I can't have that generated developer's profile by him because he is unreachable. I do have access to the apple developer account which was used to submit the app in the first place. What should I do? Revoke and create new certificates or which are my options?

Answer 1

Yes, you can revoke this certificate or you can create another distribution certificate, it's on you, but I suggest to revoke that certificate because you never going to use it

Perform following steps

1. Revoke previous distribution certificate.
2. Generate new distribution certificate by using codesigningcertificate, generated from your mac.
3. Download generated distribution certificate and install it.
4. Assign newly created distribution certificate to provisioning profile of app.
5. Download the provisioning profile and install it.

After all these steps, you are set to upload your app
