The new mobile update is crap. I can no longer simply copy last weeks invoice, change the date and send it. I have to update totals and gst rate each time?

I understand the extra steps required to update invoice details may feel different from what you’re used to. Please know we want to ensure QuickBooks Online runs smoothly for you and I’ll guide you through troubleshooting steps to address this.
 

Based on what you've described, this issue is likely related to the mobile app, which can sometimes occur due to outdated or corrupted data.
 

To resolve this, I recommend clearing your app’s data on your device. Doing so will reset the app to its default settings and help refresh its functionality.

Here’s how to clear app data:

For iOS users:
 

1. Open your Settings, then tap General.
2. Tap iPhone Storage and find the QuickBooks Online app.
3. Tap Offload App.
    

For Android users:
 

1. Go to the Home menu or tap the three dots in the upper right corner.
2. Tap Settings, then choose Refresh Data.
3. Tap Yes to confirm.
    

If the issue persists, I suggest uninstalling and reinstalling the QuickBooks app. This will ensure you’re using the latest version.

Alternatively, you can log in to your QuickBooks Online account using a web browser on your mobile device to continue with your task.
