Mobile page chart will not show up

This Chart:



Console shows data in the model for both Id and Appointment_Scheduled__c… but no chart appears.

No render conditions or context conditions.
I eliminated the old chart and created a new one just to make sure.

Added a field editor to show data in the model. Chart should be in that big blank space above.

What’s going on here?

Is this superbank or banzai? Any cross-domain errors in the console?

Banzai 7.19, no console errors
