One of the users I support reported to me that the new screen sharing feature in FaceTime stops working after about 45-50 seconds on their 14-inch MacBook Pro. They were running macOS 12.1 so I advised them to upgrade to 12.2. but that did not solve the problem. When the screen sharing stops itself without any warning the FaceTime call remains connected. You can start screen sharing again during the same FT call but the screen sharing will stop itself again after 45-50 seconds. I tested the FT screen sharing feature on two other 14-inch MacBook Pros (both running macOS 12.2), a Mac Mini (Intel, macOS 12.1) and MacBook Air (M1, macOS 12.1) and was able to reproduce the problem on every Mac. Is anyone else experiencing this?
