How do I switch the App back to classic veiw?

There is no option to switch back to the old layout directly within the app, Dale.

Please know that QuickBooks Online (QBO) updates aim to enhance efficiency by offering customizable features that consolidate all necessary tools in one location. We encourage you to explore the updated interface to streamline your tasks.

Alternatively, you can use the web version to revert to the classic interface. To complete that, navigate to the Gear icon, look and click Switch back to the previous QuickBooks experience. If this option is unavailable, your account is fully migrated and cannot be reverted.

Please feel free to respond to this thread if you have any additional questions about QuickBooks.
