Failed to download xbox360 profile on xbox one x

I tried to

buy xbox360 Red

dead

redemption 1 on xbox one x. But failed.

I tried to buy the game on PC. But also failed.

Fix the xbox360 billing site.

fyi- after many attempts at this- we found out that the profile you are trying to download inside a xbox360 game (that is being played on the xbox one) needs to be signed in on the xbox one BEFORE it will correctly download the profile inside the 360 game.

What if I did exactly that and had both accounts on Xbox one and Xbox360 same time and it still says profile not downloaded, download for live, etc

Thanks for your reply.

I've tried all that. I've even tried logging in using a different xbox profile.

Nothing I do will get the app to install on my Xbox One X.

I just don't understand why the app will download just fine on my OG Xbox One but totally fail to download on my Xbox One X even after a full factory reset. It's just baffling.

If it wasn't for the fact that it's the only app that wont install I would assume my X is faulty. But all other games and apps I try install fine.

Make 1 of the Xboxes the "Home Xbox". When done make sure privacy and sharing preferences are set on the "Home Xbox" to share. After that all the games on the "Home Xbox" are accessible by any profile added to that "Home Xbox. The other (non "Home Xbox) has to have the game purchased under that 2nd Xboxes main profile or purchased as a gift from any profile and sent to a chosen profile to be downloaded when that profile signs onto their Xbox. I have an Xbox One X in my living room controlled by my 2nd account profile. I have a Series X in my game room "Home Xbox" controlled by my 1st profile. Example; I log on the Series X with that main profile and buy/download Division 2 with all expansions and passes. I then log on the One X with my 2nd profile (main for that One X) and buy/download Division 2 with out the expansion and passes. So now a family member adds their profile to the One X, if they own the Division 2 they can play it and as much of the content that I have purchased. To play the full version on the One X someone has to buy it for that console, However anyone else that logs onto the One X with their profile that doesn't own any of Division 2 content can't play it at all. They can launch it but it will direct them to the store. Now adding Ultimate Game Pass to the One X allows profiles to download and play any games available through game pass. Remember my Series X will allow any profile added and signed onto can play any games and use the Ultimate Game Pass to download and play from my Series X. One X has limitations for profiles due to that profile owners games owned and which games are in the One X. Confusing ........ ?
