Problem: Extrusion expression button is not showing on my Extrusion group in the ribbon in ArcGIS Pro

[BabatundeDavidAdejumo]

I need some assistance with the extrusion group in the ribbon. The extrusion expression button is not showing at all.
Thank you.

This is rather strange.  What ArcGIS Pro version are you using?  I'm using ArcGIS Pro 3.3 and it's there.  I can see it in my 2D views, 3D scenes and 3D globes.  When I see general wonkiness like this, first thing I recommend is a soft reset of ArcGIS Pro to see if that restores missing functionality.  You can learn more about how to do this here.

Just simply restart the Arcgis Pro and you will find the 'extrusion expression button' again.
