When making an invoice, when I go to add a product or service the app seems to bug and bounce that screen in and out.

We can perform some troubleshooting steps so you can create an invoice, @watertribepoolsa. Let me help you how to do it.

The QuickBooks app's unusual behavior can be caused by the stored cache, which slows down performance. We can perform some troubleshooting steps to refresh data into its default state. This process plays the same role as clearing the cache from your web browser.

If you're using an iOS, follow the steps below:

1. Go to Menu ☰ and tap Help & Feedback.
2. Tap Refresh Data.
3. Click Refresh to confirm.

Otherwise, refer to this instruction for Android:

1. Go to Menu ☰, then select More Options ⋮.
2. Tap Settings, and click Refresh Data.
3. Tap YES to confirm.

If the issue persists, you can uninstall and reinstall the mobile app, ensuring that you get the most recent version of the application. To do so, you can check this page: QuickBooks Mobile App.
