I wrongly revoked the certificate of my current published app

What sort of certificate?

You tagged your post with Developer ID and revoking those is hard to do by accident because you have to contact Apple. See Developer > Support > Certificates.

Other types of certificate you can revoke yourself using the Developer website. That’s not normally a big deal because the certificate only has to be valid when you use it. For example, the Apple Development certificate you use to sign an app when uploading it to the App Store only needs to be valid during the upload process. When the app is distributed by the store, it’s re-signed by Apple.

Share and Enjoy
