Why has everything disappeared in the app on my phone?

Let's troubleshoot the application to ensure that it works properly, yalanzhy. I'm here to guide you through the process.

To begin with, please ensure that you have a strong internet connection and an updated version of the app to sync the latest data.

If the issue persists, I recommend clearing the application data of your QuickBooks Online (QBO) app. This process will reset the app to its original state, eliminating any potential issues caused by outdated or corrupted data, and ensuring your QBO app functions smoothly.

For iOS:

1. Go to the Help menu.
2. Select Reset App Data.
3. Click on OK.

For Android:

1. Proceed to the Home menu or tap the three dots in the right upper right corner.
2. Tap on Settings.
3. Select Refresh Data.
4. Click on Yes.

If the problem remains, I suggest uninstalling and then reinstalling the app. Additionally, using other supported browsers can be a good alternative too.
