My iOS app no longer has any categories and the “refresh data” button doesn’t exist anymore. I’ve deleted and reinstalled the app but that didn’t help

This isn't the experience we want you to have when using our QuickBooks Online (QBO) app on your iOS, @raiderred1.

I'll share troubleshooting steps to fix this issue and be able to utilize the categories seamlessly.

First, you can access your account on your mobile browser to see if the Categories feature you're looking for is still there.

Also, please know that the Refresh Data option to see the latest information is unavailable on iOS mobile operating systems. Thus, this is for Android users. To update your data, you can follow the steps below:

1. From the Settings tap General.
2. Click iPhone Storage, then select the QuickBooks Online app.
3. Tick Offload App.

You can refer to this article for your reference: See your latest data in the QuickBooks Online app.

Moreover, these are additional resources to help you organize your data in QBO: 

• Group products and services into different categories in QuickBooks Online
• Categorize online bank transactions in QuickBooks Online
