Why aren't invoices showing for all customers on the app?

Hi nicholajayneeyre Are you using an iPhone or android device and do you have any date filters applied to the invoice section?

I have an Android phone and no filters as far as I am aware.

Hello Nicolajayneeyre, please can you clear app data. 

• In the QuickBooks Online app:
• Android: From ⋮ button, select Settings, then select Refresh Data, and then choose Yes.
• In your device Settings:
• Android: Settings > Apps (varies by device) > QuickBooks app from the list >Storage > Clear data.

Let us know if you still have an issue once you have done this thanks.
