Error gears of war 4

Can someone assist. My friend cant join or play gears of war 4 due to an error: Failed to join squad. The session is incompatible with this game version. What does that mean? We played it yesterday but after her update it stopped working.

You have to back up that picture from your nose and mouth.

Make sure you both have the game updated. Both quit the game and start again.

Sounds like one person didn’t restart the game after the update (possible on PC) or one person didn’t apply the update.

Yep all fixed
