File Explorer

 * The Language & Region page may not offer the necessary speech recognition language support for live captions for up to an hour after first login.

Live captions

 * The enhanced speech recognition support may not be installed correctly through the Language & Region page in the Settings app on ARM64 devices.
 * Captioning performance may be degraded in non-English languages and missing out-of-language filtering in non-English (United States) languages.

Safe mode

 * Clicking Bluetooth & devices and Personalization pages may crash the Settings app due to an overrun of a stack-based buffer.
