You can automatically download a new project to your device in Field View if the auto-download function has been selected for that project. You will need to be assigned to the project in order to see it. If the auto-download function hasn't been selected, you should receive an email with a QR code for that project instead.
The following needs to be correctly configured for the project or you may not see it in the list of available downloads. The project needs to be:
Active
Past its start date
Not past the finish date
