Detected shortly after the release of iOS 13.4 and macOS 10.15.4, the "FaceTime" issue prevented iPhones and iPads and Macs that are running these updates by making or receiving "FaceTime" calls from older devices, that cannot be updated, e.g. B. "iPad" 2, "iPad" of the third generation, iPhone 4S, "iPad" mini of the first generation and iPod of the fifth generation touch.

– Fixes a bug in the Settings app where the selection of Bluetooth from the quick action menu on the home screen failed.
