1. Switch your connection: Toggle between Wi-Fi and mobile data to check if the issue is related to your network.
2. Close and reopen the app: Fully close the QuickBooks app, then open it again.
3. Restart your device: Power off your iPhone completely, then turn it back on.
4. Reinstall the QuickBooks app: Remove the app from your device and reinstall it from the App Store.
