"Awaiting Device Activation" after joining iPad through Apple Enrollment

Hello, we have a few iPads that we've enrolled in Apple Business Manager through Apple Configurator 2. We can see them in the Apple business portal. In Mobile Device Manager, we've been able to enroll them using "Apple Enrollment," but we just see it sitting there "Awaiting Device Activation." What do we have to do to finish activating it?
