I downloaded forza horizon 4 but it wont show up

All of my Microsoft and Xbox games are downloaded on my external drive including the previous Horizon, which is Forza Horizon 4. I changed where new apps are stored when downloaded from the Microsoft store to my external drive but it still wont download Forza Horizon 5 to my external drive. On the Xbox app it wont show my external drive as an option to download to. I am able to download any game from the Microsoft store and Xbox app to my external drive except Forza Horizon 5.

Can you please be more specific?

Did you download a game and it is not showing up?

Or are you referring to Forza Horizon 4. If it is Forza Horizon 4 you still need to go and down load it. The betas does not automatically download the new game.

I just got forza horizon 4 ultimate edition(not the digital download) and it just wont read or download the game the DLCs are downloading but its supposed to give early access

I've done this at least 3 times and sadly it hasn't worked. What I noticed was some games from the Game Pass let me download for example I can download Forza Horizon 4, Astroneer, and a few others but games like Forza Horizon 5, Back 4 Blood, and Outlast 2 won't let me download, the drives still don't show up. Any ideas on why some games the drives come up and some don't?

Thanks for the response, it seems to force me to download "Forza Horizon 4" first. When I click pause it's download and then try to start download on "Forza Horizon 4 Standard Edition" it stays at "Downloading" and starts Downloading process of "Forza Horizon 4". I also tried logging into my account on different computer which worked.
