Better together beta wont activate

I activated the Minecraft windows 10 better together beta through the insider app hub, when I went into my mcw10 it was still 1.1.5, I even tried checking for an update, re-installing the app as a whole, restarting my computer and even opting out of the beta and then re-joining and nothing will still work. I cant get the 1.2.0.7 update to work.
