Known issues

We’re looking into an issue where some devices booting from eMMC storage may bugcheck when resuming from hibernate.

We’re looking into reports of the update process hanging for extended periods of time when attempting to install a new build.

We’re looking into reports that taskbar preview thumbnails aren’t rendering consistently (showing a blank area).
