Hi, info.
I'll make sure you'll get to see your suppliers and continue categorising your receipts in the QuickBooks Online (QBO) mobile app.
In this case, the application may become obsolete over time, which prevents you from accessing the lists of suppliers. You'll want to uninstall and reinstall the app so you can perform more tasks and get your hands on additional functionality.
If the issue persists, I recommend you to get in touch with our Technical Support Team. That way, they can securely check into your account setup via a screen-sharing session and guide you through the resolution process.
Please be aware that the scheduled times for the support are available from M-F, 8:00 AM to 10:00 PM, and S-S, 8:00 AM to 6:00 PM. See this article for further details: QuickBooks Online Support.
Once everything is good, you can check out this article for future reference in uploading and categorising your receipts: Upload your receipts and bills to QuickBooks Online.
If you have other concerns or clarifications in managing your suppliers, let me know in the comment section. I'll be happy to help you.
