Play Together Minecraft

Hello, I'm having a really stressed out problem with my game, I can't tell what is going on because I really don't know. I do everything in my power to fix such thing but nothing is seems to be working. Two days ago I've received a message in Minecraft Xbox One Edition informing me 'there's a new Minecraft update available, if I would like to visit the game store to download it, in the game store"? I clicked on the linked then it takes me to the game store. In the game store it shows another Minecraft by the name Play Together, It appears to be a new server update. When it was finish downloading off my console and I was in the game menu it say would you like to download your old Minecraft Xbox One Edition to the new Play Together Update? I pressed yes from there it will show all my game files I've but when I pressed on download it started to work. But when it get to the second option with the World conversion the game will goes black and send me back to the Xbox One Home. Each times I tried this it is the same issues. I've played the game for 1,600 on the Xbox one Edition, the file is pretty big. When I looked at how much spaces on there it say 191.1 MB.. Is the game mode I've to big to be transfer to the Let Play Together update that was released a few days ago? For some reason I'm stuck and can't play my world. The same thing with my friends who have their file worth 169.2 MB who's been playing the game a while back now. the game work back on the Minecraft Xbox One Edition but it doesn't allow world over 191.1 MB to be transfer. Can you guys please look at this together and find us a solution is all I asked. I provided two screen shot so you can get a more idea in the issues. But the World conversion will kick me back to Xbox one dashboard and the second picture shows you the safe and file MB I've stored in the game itself. And yes I've bought the full game 2 days ago if you're just wondering. 🙂
