26 March 2019 my kid's minecraft also switched to Beta without opting in. I'm attaching pictures. On the top of the Minecraft sign in screen, small white letters have appeared that read "beta 1.11.0/7 Gui:4.00" and a second line under that that reads "xbox_one_s, , Xbox One 5 10.0.17763.4088. FP560.0 Server Time: 0.0ms/50ms. Men: 853MB. Highest Mem:1045MB". In the bottom right hand corner of the sign in screen, v.1.11.0.7 appears. All worlds have switched to having the new villager appearance. Villagers will not trade. No progress appears to be lost in the world. Images of an affected world are attached.
