Answer 1

These problems are apparently caused by the certificate. Apple completed the Organization Unit in the certificate. Therefore, you need to request a new certificate and install it. The field will be filled in and your application will work correctly.

Answer 2

Just go to your certificates in Keychain, Right Click → Get Info → Trust → find the field with the name “When using this certificate” → Select the option “Use system default”.
