Staying signed in
Section titled “Staying signed in”The app keeps you signed in, and each time you use it your sign-in is renewed. If you haven’t opened it for a while, it asks you to sign in again. To sign out, tap the person icon at the top, then Sign out.
If job forms are still waiting to upload when you sign out, Astragal asks first. The sign-in screen then shows how many forms are saved on the phone. They upload when you sign in again; anyone else from your company who signs in is asked whether to upload them. See Working with no signal.
