My QuickBooks app Will not work soon as I press on it it glitches it takes me straight back to the home screen on my iPhone

Hello @info1323,

Thank you for posting here in the Community. Let me help you fix the mobile app so you can access QuickBooks.

There are times that unusual behavior happens in the mobile app because of the existing cached data. To fix the issue, I recommend you perform some troubleshooting steps.

Please start by clearing the app data. Refer to the steps below.

1. From the Menu ☰, select Help & Feedback.
2. Click Refresh Data, then hit Refresh.
3. Close the app.
4. Power down and restart your device.
5. Reopen the app.

If you get the same result, you can re-install the app to start fresh. This ensures that updated security settings are downloaded. Please check the following article for the steps: How to download the QuickBooks Online mobile app (iOS app).

For additional reference, you can use the following article to learn more about the suggested browser for iPhone: QuickBooks Online access for mobile devices.
