Hello !

I have the same problem trying to Group by on a Single Select field.

Thank you !

Hello again @Andy_Scanlon !

I just found a workaround. The problem is that the Group by function doesn’t seem to work with Single or Multiple Select fields.

What I did is create another column with a formula just to transform the Single/Multiple select field into a string :

{Your field}

You should now be able to Group by on the new column you created !
