In my organization, we have one person with the Change Manager role.  We have several other admins with the ChangeApprover role only.  I submitted a test change (I have neither Change role on my account) and one of the admins with the ChangeApprover role was able to successfully approve and reject my change.

However, when the tech that is designated as the sole Change Manager submitted a change, the techs with the ChangeApprover role are unable to approve the change.

Can someone explain what I might be missing?

Thank you.
