Reporting - What happened?

I regret hearing about your frustrating experience, @Peggy4. Please know that this is not the level of service we strive to provide. I fully understand how beneficial it would be to have the report function as it was previously in QuickBooks Desktop (QBDT).
 

As I've checked, there is an ongoing investigation into the reports collapsing or expanding only to the account level. Our engineering team is currently looking into the issues you are encountering.

Kindly notify me if you have other concerns with handling your reports in QuickBooks Desktop. I'm here if you need further help and provide you with the necessary assistance you may require, @Peggy4. Keep Safe!

It's a bug in the latest 'improvements' to reports. It looks like no one tested those changes, as there are many people reporting several issues with it, though Intuit reps here like to pretend there's no issue.
