Just in the past week our custom field "PO" has been removed. We can no longer access it all through the mobile app. The only way to circumvent the issue is to use the web browser on the phone to log into Quickbooks online. However, Quickbooks has been trying to force us into using the app for years now. Now that we are using it they are taking away features that we need. ALL OF OUR INVOICES REQUIRE PO's, taking away this option is completely ridiculous!
