was "Invalid by the issuer of this certificate" it's almost dead.

iOS for a new certificate, for several days, not "the issuer of this certificate is invalid", is unable to publish the package.

On the Internet, "the issuer of this certificate is invalid", double-click the certificate Select "Always Believe", you can hit the release package. But publish to the last ITMS-90034 error.

It's killing me.

Later found to update the WWDR Certificate certificate. WWDR Certificate Certificate: Https://developer.apple.com/certificationauthority/AppleWWDRCA.cer

After downloading, double-click to open the installation, you can see the certificate has been updated.

However, the installation of the development certificate and the publishing certificate still shows "the issuer of this certificate is invalid", no language

After a long day, found to delete the expired WWDR certificate certificate.

Open keychain, show expired certificate (hidden by default), click Show--Show expired certificate

After deletion, the certificate is OK, then the release is also normal, done!
