Why is there no longer a revert arrow in the QuickBooks app on my iPad Pro?

I can help you figure this out, sheltontipton.

The QuickBooks Online app installed on mobile devices requires version 11 or higher for iOS and version 7 for android devices to work. You can refer to this article to learn more about the supported versions of iOS devices: System Requirements For QuickBooks Online. Accountant, Payroll, and Self-Employed.

You'll want to update the app to ensure you have the latest features and fix this unexpected behavior. I'll show you how:

For Android:

1. Go to the Start menu and open the Store window.
2. Select the profile icon.
3. Choose Downloads and updates.
4. Locate the QBO desktop app.
5. Click Get updates.

For iOS:

1. Open the App Store on your Mac. 
2. Select Updates in the App Store toolbar.
3. Locate the QBO desktop app. 
4. Click Update.
