Hi everyone. Dealing with the error message while creating invoices could be a challenge. I'm here to provide you with some updates about the error.

If you're using the QuickBooks Online (QBO) mobile app on an Android device, let me add this article for the troubleshooting steps to fix the problem: Fix common errors in the QuickBooks Online mobile app for Android.

On the other hand, if you're using the app on an iOS device, please know that our product engineers are actively working on a fix for the error message you encountered when creating invoices. I encourage contacting our phone or chat support team to add you to the list of affected users and be informed once it's resolved. Here's how:

1. In your QuickBooks Online company, go to Help (?).

2. Select either of these tabs:

• Assistant tab and type Talk to a human.
• Search tab and click on Contact us to connect with a support expert.

3. Choose how you want to reach us (phone or chat).

In the meantime, I suggest utilizing the mobile browser for creating your invoices.

Once the issue is resolved and you've received customer payments and have the need to edit them, I'm adding this article as a future reference: Edit an invoice payment using the QuickBooks Online app.

If you have additional details to share when you experienced the error using the QBO mobile app or other QBO-related concerns, we'll be here in the Community to help.
