I need to do my bookkeeping but I have somehow opted into something called BETA which won't allow me to do hardly anything..how do I get my original quickbook back?

Thanks for checking out the Community space, cardmanltd.

From time to time, we roll out design updates and beta features to create a more aesthetically-pleasing work environment. We aim to make bookkeeping tasks easier and faster, which will ultimately save you time.

I would love to help you, but I just need some details about your concern. Can you tell me which area in QuickBooks Online you're working on? 

Any additional information or a screenshot of the interface will be greatly appreciated. Looking forward to your reply. Have a good one!
