回答1:
This issues seems to be caused by the certificate. Apple filled the Organization Unit in the certificate. So you need to request a new certificate en install that one. The field will be filled and your app will work properly.

Just go to your certificates in Keychain , Right Click -> Get Info -> Trust - > find a field with name "When using this certificate"-> Select "use system default" option.
