As of March 2017 most of my Xbox One articles and videos are now outdated. They show my son and I video chatting and gaming together on the XBOX One. He lives on the other side of the country so we did this a lot. It was a great way to hang out with him so losing the snap feature with video chatting is very hard to accept.
I am trying to stay positive about future updates but I was heartbroken when I found out. I recalled “upgrading” the Xbox software just as my son was saying, “Dad, I don’t think we can video chat and game on the Xbox One anymore”. I have read that the snap feature is being replaced with picture-in-picture (PiP) overlay (with the Skype app I think).
I kindly ask the teams at Skype and Xbox to please move this feature to the top of the pipeline. I will reach out to both companies to see if I can get more info and will update when I learn more.
