Good day, houndall. I've got some troubleshooting instructions to verify if the app's data causes this odd behavior in your PDF file.
There are times when the QuickBooks app data affects its performance. Resetting refreshes it into the default state. This process plays the same role as clearing the cache from your web browser. To start, follow the steps below for an iOS:
Go to Menu ☰ and tap Help & Feedback.
Tap Refresh Data.
Click Refresh to confirm.
Otherwise, refer to this instruction for Android:
Go to Menu ☰ then tap More Options ⋮.
Tap Settings, then Refresh Data.
Click YES to confirm.
If the issue persists, uninstall and reinstall the mobile app. It will help you get the most recent version of the application.
