Hi there, @Beths14. QuickBooks Online automatically updates to the latest version and there's no option to revert to previous versions. This is because QBO is a cloud-based software that maintains one current version for all users to ensure security, compliance, and data integrity.
While the interface has been updated to provide a more streamlined and intuitive experience, please be assured that your core workflows, accounting features, and data remain unchanged. These updates are specifically designed to improve overall performance and help you navigate your books more effectively.
To learn more about the updated interface and discover its features, check out this article: Explore QuickBooks on the Intuit Platform.
Let us know if you have any other QuickBooks-related questions, and we'll be here to help anytime.
