Graduated symbology not finding all values with 1:M joined table

I am working on a time animation where I would like the symbology to be graduated.  I am using ArcGIS Pro 2.0.


I have one polygon which is joined to a table containing the temporal data and values for the symbology to be taken from. Polygon ID is Area1 and the subsequent temporal data has a field with Area1 next to all of the time and values I want. The join itself appears to be working as when I skip through time the labelling changes to reflect the value in each time field. 


However when I try to add graduated symbology it only finds the initial value from the join and does not allow me to use all of the values to create the symbology I want.


This blog says it is possible in ArcMap so I would presume it should also be possible in ArcPro.


Can anyone offer any assistance?


Thanks in advance.
