watchOS 6.2.1 was not the only new system released by Apple yesterday.
As it turns out, yesterday evening a new version of macOS Catalina was released by the giant from Cupertino.
Yesterday’s update, like watchOS 6.2.1 and iOS 13.4.1 and iPadOS 13.4.1, fixes the FaceTime error that prevented users from connecting to older iOS devices. In addition, the new version of macOS also fixes the USB-C port error.
You can download the update by going to System Preferences – Updates.
