I recognize how convenient it is to use QuickBooks on your iPad and understand how updates can disrupt your workflow, Reliablemedicalrepair.

First off, could you confirm if you're encountering any error messages while trying to use the QuickBooks app? Any additional information about the issue would be greatly appreciated, as it could help us provide a more accurate resolution.

Since you updated the application to the latest version yesterday, I recommend clearing the application's data to ensure that outdated or stored data doesn't interfere with its performance on your device. Sometimes, residual data from previous versions can hinder the proper functioning of new updates.

Here's how you can clear your app's data:

1. Open Settings and select App.
2. Locate and choose the QuickBooks Online app.
3. Tap Offload App to remove the app while retaining its data.

In the meantime, if you're unable to use the app, you can temporarily access QuickBooks Online through a browser version to manage your essential tasks.

Here's how:

1. Open Safari, Chrome, or another preferred browser on your iPad.
2. Navigate to the QuickBooks Online website and sign in with your credentials.

Let us know how it goes and if you require further assistance.
