On IPad app when invoice is saved app crashes and has to re-open to send invoice via email. This does not happen with estimates.

Thank you for contacting us about the issue when saving the invoice on the mobile app, gasandsparksltd.

Let me help you fix the QuickBooks app that keeps crashing on your iPad device. You can start by updating the software or clearing the app data.

The app updates usually contain patches to fix problems identified with the app. To clear the data on the app, follow the steps below.

1. From your phone's settings, select Settings.
2. Select General and choose iPhone Storage. 
3. Select an app that's taking up a lot of space. 
4. To free up the storage without deleting the documents and data for the app, select Offload App.

Once done, re-open QuickBooks and try to save the invoice. If it still crashes, you may need to delete the app and re-install it.

Please know that QuickBooks Online requires iOS 11.1 or newer. Check out these links to get the app and what requirements you need.

Once all set, you can create and save again the invoice on the app. You can also log in to your QuickBooks account via a web browser and manage your invoices from there.
