Hello there, @Nuwil Engineering.

Thanks for getting back and providing a screenshot.

The page you have is the new interface once you subscribe to QuickBooks Online (QBO). For now, you can customise how you want the menu to look. 

Here's how:

1. Choose the Menu settings at the bottom.
2. Click Customise this menu.
3. Select Bookmarks.
4. From there, choose and reorder pages to bookmark.
5. Click Save.

I understand that you wanted to bring back the old interface. The Community recognises feedback and suggestions from customers like you that can help us improve our product and services to our customers' delight. I suggest sending feedback while this feature is not an option.

To send feedback, follow the below steps:
