You might want to go into your account in the JSS and check the privileges. Sometimes these upgrades cause you to not have the appropriate privileges to see items in the JSS. Its happened before.
@CasperSally I noticed that as well. The /enroll link still works and is a bit different that 9.3x. It actually gives feedback on what is happening.
@mm2270][/url Yup. Thanks! Hate it when I forget to check those.
Just as a note for anyone else that might see this:
In the last version, under permissions/JSS Settings there were two options "User Initiated for Computers" and "User Initiated for Mobile." In 9.4 they are combined into one, likely why it 'unchecked' it for me.
