Issue with summarize_column_by parameter on Trial Balance report

Hi everyone,

I’m working with the Trial Balance report via the QBO API and running into an issue with the summarize_column_by parameter.

It works correctly when I set it to Month, but when I try other values like Customers or Classes, the data still comes back summarised only by Account.

Has anyone else run into this? Is this expected behaviour, or am I missing something in how the parameter should be used?

Thanks in advance!
