I hear what you're saying and can see how having to navigate between the old and new interface with your three accounts. The update to the interface is still rolling out, but before too long, all of your accounts should be on the same layout.

There isn't currently a way to toggle back to the old interface. I recommend submitting feedback about this through the Gear icon. We value and appreciate the feedback from our customers and your message will be forwarded to our product development team for consideration.

Let me know if you have more questions!
