I know that on the telephone, assuming that one wants to be formal/not familiar, one would use «Auf Wiederhören» (meaning "until I hear from you again"), and that in person «Auf Wiedersehen» ("until I see you again") is used.
With the invention of video calling, such as Skype, Zoom, etc., what would a German person use to close a conversation on a video call? Does one use the normal telephone farewell, the in-person farewell, or something completely different?
