Hello, dhosei.

We can perform troubleshooting steps to help fix about generating income statement report in your QuickBooks mobile app. 

When the application is not fully functional, it's recommended to clear its cache files. This is a helpful initial step to resolve any sort of issue. 

Follow these steps if you're using an iOS device:

Once refreshed, restart your mobile phone, and check if you'll be able to generate the report you needed in your mobile app. Just in case the issue persists., uninstall and reinstall the QuickBooks Online mobile app. Let me share this article with you for additional reference: Mobile App FAQs.
