I'm here to ensure you can access your QuickBooks mobile app to utilize the snap feature and track your mileage, Tgreer.

What do you mean by the link that doesn't work? I click the one provided by Archie_B, and it opened and worked for me. 

To ensure you can access the app, let's update your iOS (iPhone) or Android to their latest version. Updating them is necessary to help you access new features and fixes. 

If the issue persists, let's uninstall and reinstall the app to refresh its setup.

Otherwise, I suggest reaching out to our support team. They have the necessary tools to check your account in a secure environment and help investigate further your concern.
