Known Issues in 2018.4.33f1
macOS: If the Android Tools are not installed through the Hub, macOS 10.15 (Catalina) default security settings will prevent the Android NDK binaries being executed. These settings have to be changed or a signed Android NDK (r16b) will be needed to build Android. More information here: https://developer.android.com/ndk/downloads/older_releases.
Package Manager: Immutable packages altered by the API Updater are reverted to their original state when packages are resolved, which can lead to slower import performance in that context.

Windows: The Cursor is visible when Cursor.visible is set to false and new InputSystem package is used (1273522)
