Hello, 

I started my game on the xbox one version of minecraft then I transferred the game to the new version of minecraft for console (bedrock) and I just realized that the new structures are well generated but the end portal is no longer found on my map. I've switched to spectator mode and the strobghold is obstructed by rock and is only a few blocks long with no portal. The seed of my initiated world on my xbox one version is: 218451881 

But when I use this seed on the new version, I don't get the same map.
