I'm not seeing a Mac top bar menu on my iPad side?

When you're running Luna Display, and the top menu bar is missing on the iPad side, the best places to check is the Mac's System Preferences

Especially General or Mission Control.

In General:

Open your Mac's System Preferences, and select General; in that menu make sure that "Automatically hide and show the menu bar" is disabled.

In Mission Control:

In your Mac System Preferences, go to Mission Control, and check that "Displays have Separate Spaces" is enabled. 

If this is not enabled, click for the check mark, and log out of your Mac or restart the Mac itself.

After the restart this should be fully set.
