Needed to collaborate with someone on a document, editing on Macbook Pro (MBP). Made FaceTime audio call, but then switched to video. Top of screen claimed "call failed" but we were still talking. Then the iPad began begging me to answer the call! It gave up and we were still on. iPad was not a call from someone else.
Something else disconnected us, and when I called again, this time the iPad did not interfere.
Is the first just a fluke, or must I do something to prevent the iPad from trying to hijack a call on the Macbook? (Hopefully something other than shutting it down!)
