It's only Wednesday, but Microsoft has already released its second Xbox One Insider Preview build to the Alpha ring this week. 15046.1001, or rs2_release_xbox_1703.170226-1700, follows 15045, which was released on Monday.
Preview Alpha is meant to receive two to three builds per week, and if Microsoft continues on its pace this week, it would be the first time that three builds have actually been achieved. Beta is supposed to have one or two, so given the modest changelog for 15046, it seems reasonable that the Beta ring might stay with 15045, which was offered last night.
Today's preview only lists "miscellaneous fixes and improvements" under the section of fixes. As always though, there are some known issues:
Xbox Accessories
“Portal” accessories used with games like Skylanders, LEGO Dimensions, and Disney Infinity are not recognized.
The Xbox Accessories app Device Details page may appear blank.
Workaround: Update the device firmware, and view Device Details on a console not enrolled in Preview.Copilot does not function at this time. You can disable Copilot from the power menu (hold the Xbox button on the controller) if desired.
Cortana
If Cortana was enabled prior to entering connected standby, you may encounter an error when resuming from connected standby.
Cortana may take a long time to respond when activated while playing certain games.
Scheduled Cortana reminders will not provide a notification if the user who created the reminder is signed in, but not the current active user.
Using voice dictation sometimes causes the virtual keyboard to become unresponsive.
Notifications
Some users may not receive certain types of notifications.Game Clips
Workaround: Manually view game clips in Profile > Captures > Manage captures and post to the Activity Feed.
After capturing a game clip, the game clip fails to automatically post to the Activity Feed (if your profile is configured to do so).EA Access
The EA Access app may indicate you are not an EA Access subscriber when you are. This does not affect your ability to download or play games from the Vault, or receive discounts on EA titles.Screen Dimming
The screen may dim after a short amount of time while viewing videos in certain apps (Hulu Plus).Settings - Ease of Access
When enabling the Mono output setting in Ease of Access - Audio, Settings becomes unresponsive, crashes, and fails to launch on subsequent attempts.
Workaround: To launch Settings, perform a hard reset (hold down the button on the front of the console for five seconds until it fully powers down, then power it back on).Settings - Display & sound
The Audio output page is under construction and some of the new settings are not yet functional. New support is planned for Dolby Atmos for home theater, Dolby Atmos for headphones, and more in upcoming builds. An announcement will be made when these new features are ready to try out; enabling these settings now will have no effect.Wireless Display
The Wireless Display app fails to launch and immediately crashes to Home.
Many of these known issues have been present since the first Creators Update preview for the Xbox One, such as the Cortana ones. The update should arrive in all of its glory this April, so everything should be fixed by then.
If you're on the Preview Alpha ring, you can grab the build by going to Settings -> System -> Updates. If not, you can work your way up by completing Surveys and Quests in the Insider Hub, but if you become inactive, you can be demoted as well.
