I don't really use notebooks, so what I'm about to suggest may be erroneous? How about copying that external notebook file into the project folder then follow the instructions you link to, to add it to the project? ... View more

Edit it to remove the space. Nothing wrong with tweaking the ini file. ... View more

This can be easily done and you were almost there. The trick is it set up the field map with concatenation. So input data is this: I want to join the polygon ID's to the lines, thus the Spatial Join is set up as: The field map was set up as below; take note of the ACTION: Run the tool and the output is a new line dataset with concatenated polygon ID's.     ...

Just a shot in the dark, is your workflow creating schema.ini files? More info here, may be they are confusing ArcPro in someway? ... View more

I personally have found trying to change the labels in symbols always a bit flaky through direct manipulation of arcpy classes, but may be that's just me... Anyway an alternative method is to access the CIM object module for fine tuning layer properties, this includes symbology.  As you say in your question you can easily change the decimal places through Advanced symbology options in the UI, so lets replicate that!   import arcpy # Get handle on layer in first map p = arcpy.mp.ArcGISProject('CURRENT') m = p.listMaps('MAP')[0] l = m.listLayers("fc_AreasMerged")[0] sym = l.symbology # Change rounding value using CIM lcim = l.getDefinition('V2') lcim.renderer.numberFormat.roundingValue = 2 l.setDefinition(lcim) # Update/refresh renderer sym = l.symbology sym.updateRenderer ('GraduatedColorsRenderer') l.symbology = sym     If you want to get into manipulating CIM, best bit advice I can give is get hold of the CIM viewer AddIn, this allows you to see the CIM for a layer selected in the Contents Pane. I couldn't live without it! ... View more
