Only one device can be in use to stream games, whether at NFLSUNDAYTICKET.TV or on a mobile device using the NFL SUNDAY TICKET app.
If you'd like to switch to another device, no problem! Just remember to sign out of the current streaming device before signing in to another. It may take a moment or two after sign out.
Does anyone know if this is accurate?
