Hi there, @Cooper1948.
I'll lay down some information about the purpose of the QuickBooks Desktop Mobile app.
QuickBooks Desktop Mobile app is used to scan or upload receipts and bills and attach transactions to documents with seamless integration in QuickBooks Desktop.
With that, the bank deposit feature is unavailable in this application.
Moreover, you need to install or download QuickBooks directly to your computer to process deposits.
Alternatively, I'm adding this article if your having an issue in QuickBooks Desktop Mobile App: Troubleshoot QuickBooks Desktop mobile app.
