I used to be able to have 2 people making invoices in qb app. I can no longer do this. What has changed

It's best to start by checking your users' access, Jones. Allow me to elaborate further.

Since you mentioned that you usually have two people creating invoices in your QuickBooks Mobile app, it's essential to verify if the access permissions for your users have not accidentally changed. This could be the reason why you can no longer create invoices simultaneously with the other user.

However, if your user has the necessary access as mentioned above, we can then proceed with basic troubleshooting steps to resolve any app-related issues that are generating the error message you're user have received.

Follow the steps below:

For IOS devices:

1. Go to Settings, then tap General.
2. Tap iPhone Storage, then tap the QuickBooks Online app.
3. Tap Offload App.

For Android device:

1. Go to Menu, then tap More Options.
2. Tap Settings, then Refresh Data.
3. Tap YES to confirm.

If the issue persists, you can then uninstall and reinstall the application to make sure that your application is up-to-date.
