Hello there, @chris102.

Let's isolate this behavior you encounter when saving expenses in your application.

The unresponsive page happens when an application encounter system issues due to a stored cache. As an initial step, we can clear the app data to optimize its performance. Sometimes, the stored cache can cause unusual behavior in the system. Here's how" 

In the QuickBooks Online app:

1. Go to the Menu ☰
2. Select Help & Feedback
3. Click Refresh Data
4. Then press Refresh.

In your device Settings:

1. Select Setting General iPhone Storage.
2. Choose an app that's taking up a lot of space.
3. Click Offload App to free up the storage without deleting the documents and data for the app.

Once completed, reopen the application. In case you're getting the same error in the future, we can uninstall and reinstall the QuickBooks Online app. This way, you can refresh the connection between your app and your phone. Let me show you how: 

1. Uninstall the app.
2. Open the App Store on your device and search for QuickBooks Online.
3. Click Free and then Install.
4. Sign in using the same user ID and password that you used when you signed up for QBO.

To learn more about some quick steps to fix most app-related issues, you can open this article: Troubleshooting Quick-Start Guide for the QuickBooks Online app. While working with QuickBooks, you can as well check out some related topics from our help articles as additional resources for additional tips and resources.

Keep me posted on how it goes. I want to make sure this is taken care of. You have a good one.
