I just got a new phone and almost all my invoices are missing when I signed into the app

Hi there, 

Glad to have you as a new member in the Community. I'll be happy to provide the info you need so you can continue to manage your work with ease using QuickBooks. 

Based on what you've described, I recommend uninstalling and reinstalling the app. This is a great way to troubleshoot issues that may be affecting the app. By reinstalling the app, this ensures you're on the latest version of the mobile app. Also, are you able to view invoices while using a web-browser instead of the app? 

Feel free to let me know what happens. I'll be one message away.
