This issue has been going on since day one of the new Xbox Minecraft version.  On the Minecraft Xbox One edition whenever I played in a friends world or my own world and I leave the game app for a second to go to the dashboard or check out the Microsoft Store then come back to the game it would resume to what I was doing.  On this version of Minecraft if you leave the game app for a split second to go to the dashboard and back to the game it shows the Mojang logo like it’s starting up the game again and it kicks you out of your world or your friend’s world and you have to rejoin it again.  Anyway of fixing that or is that intentional?  Thanks.
