Is there a way to disable the modern view for reports? I only want to use the classic view.

Thanks for posting in the Community, emily-muggeridge!

Appreciate the feedback you have with the modern view for reports. Currently, the report is still a beta feature in QuickBooks Online and we're unable to turn it off or disable them.

We can click on Switch to classic view button to be able to revert to the old view for reports in QBO.

Furthermore, you can share your thoughts about this feature after clicking the Switch to classic view button. Or you can send your feedback in product by clicking on the Settings icon or Cog wheel icon, and click on Feedback.

Additionally, you can check out this article to learn more about how to focus on the details that matter most to you when you pull up reports in QBO: Customize reports in QuickBooks Online.

Post again in the Community if you have further concerns. I'll get back to you the best way I can.
