End portal falling in void bug

Hi, there is a serious End Portal bug where when I enter the portal I fall into the void before the platform even spawns, I don't know if this has to do with the End generating slowly after I spawn because I second and third tested the bug and they both seem to work where I spawn on the 'spawning' platform. It is not has I had feared though it not being a game breaking bug as I would not have able to progress further and "finish" the game, since it does the work the spawning platform the second time I entered. I hope this addresses the issue that XBOX players have with world generating slowly when spawning in a world it being overworld/nether or end and that you are to fix or help with this issue.
