Bugs and quirks[edit | edit source]
- The update process to this build has a chance of hanging for extended periods of time.
- Some pinned websites do not work with the new taskbar experience.
- Live preview doesn't work for pinned site tabs.
- Pinned sites don't show all open tabs for a domain. A workaround with this issue is to pin the site’s home page rather than a specific page.
- Syncing may not work properly in the Mail app with certain mail services.
- If you open an Office document from File Explorer, it may appear to be blank. To workaround this issue, open the selected document from the app instead.
- Some Office applications may either crash or go missing if you update to this build.
- Some devices may randomly encounter an
KERNEL_MODE_HEAP_CORRUPTIONBSOD. - There's a chance of the Settings app crashing if you open Manage Disks and Volumes.
