Can't download Forza Motorsport 6: Apex

everytime I try to download Forza Motorsport 6: Apex, I get an error. I will try to get the error message next time it happens, as I’m retrying to download now. My problem is I leave it to download, and when I come back after an hour or so, it will give me an error, and when I press the x, it leads me to update it, which I assume just re-downloads the game (21.59gb) So can someone help me out please?

I had the same problem and managed to download the game from My Library section in the Store App. As far as you try to download it once, you get the license of the app so you can find it there.
