Hi, Janice.
Since your app isn’t working with your Apple device, let’s first check if your device meets the system requirements. The QuickBooks app works best on iOS 16.0 or newer, so please ensure your device is updated to the latest version. Using an older iOS version may lead to compatibility issues.
Several factors can slow down the QuickBooks app, including limited storage, cache buildup, weak internet connectivity, or server problems. To resolve these issues and keep the app running smoothly for your business, please try the following steps:
- Switch between Wi-Fi and mobile data to test your connection.
- Close and reopen the QuickBooks app.
- Restart your device.
- Uninstall and reinstall the app.
To free up space without losing your app’s documents or data:
- Open Settings and select General.
- Tap iPhone Storage, then choose the QuickBooks Online app.
- Tap Offload App to remove the app but retain its data.
While troubleshooting the app, you can access your account through the QuickBooks Online browser version to complete critical tasks in the meantime:
- Open Safari, Chrome, or another browser on your iPhone.
- Go to QuickBooks Online website and sign in with your credentials.
