Please log in now. Session Timeout" If you experience a timeout error on the FastField app, there could be a couple of reasons why: - You've been logged into the app for more than 8 hours. - Your user account is logged into the app on another device or being used in an API service. To fix the issue, there are a couple of things you can try: 1. Double-check that you're not logged into the FastField app on another device. 2. Make sure your device's time and date settings are correct.
