• If your console hasn’t downloaded and installed the update by 1:00 AM PDT 9/6/2017 (8:00AM GMT 6/9), you will be prompted to do so at that time.

2. Select Light.
· Game invites are moving from Action Center to the Multiplayer tab of Guide and Recent Achievements will now be in the Achievements tab.

• Movies & TV and Misc Media Apps
Black screens during movie playback have been fixed as has Fast Forward.
• Light Theme
There are some known visual contrast issues in messaging, the entertainment twist and the Mixer twist – you may see white one white. Fixes will be coming soon.
When using Arabic or Hebrew language and signing in with a profile using the “Lock it down” security preference, the sign-in screen which requests Microsoft account e-mail address and password is distorted. This does not affect the profile if it is set to use the “Ask for my passkey” or “No barriers” security preferences.
Workaround: Set the console to use another language, sign-in, and set the profile’s security preference to “Ask for my passkey” or “No barriers”. Alternatively, you can still type in your password as normal using the virtual keyboard though the screen is distorted.
When using Hebrew language, Netflix fails to launch.
• Minecraft Better Together Beta
Other games fail to launch after launching the Minecraft Beta.
Workaround: This occurs if the Minecraft Beta is the first game launched after powering on the console; launch another game before Minecraft to avoid this issue. If you are stuck in this state, hard reset your console.
