Hi @Jeffio.
I appreciate you looking at ways to switch back to the earlier version of your QuickBooks Online mobile application. Currently, the option to roll back to the old version is unavailable. I know how beneficial it is to have this feature, so you can switch back to the previous version when you're uncomfortable with the changes in a specific app.
You can consider changing your iOS app updates preferences to turn automatic updates off moving forward. This way, you won't have to roll back an application version and review new updates before you decide and install app updates. You can change this by going to your iOS Settings. Select App Store to turn off or on App Updates. You can reference this article: How to manually update apps on your Apple device.
On the other hand, if you want to optimize your experience while navigating QuickBooks Online, feel free to check our QuickBooks Online system requirements and your access for mobile devices.
As always, don't hesitate to comment if you have other QuickBooks concerns. I'll be here to help you more. Have a good one!
