I have the Xbox Series X.

I have the Xbox one X project Scorpio, I was told that the game can be downloaded in any serie X or serie S (included mine), thanks for the help!!

Game can only be downloaded on a Series S and Series X, but not an Xbox One X. Xbox One X is not the same as a Series X.

Not really...

Xbox Series X games / upgrades / updates has to be installed onto the Series X internal or expansion card SSD,

You can have Xbox One games on your external hard drive that will get an Series X upgrade but the games will need to be transferred to the Series X and then the Series X upgrade will need to be downloaded onto the Series X SSD,

As an example...

I have Marvel Avengers on my external hard drive that will get the Series X upgrade and I will transfer the game over to the Series X SSD ready to download and update the game to the Series X version when available.

I think they have given me the wrong disc version

On the disc is says "Xbox One - Xbox Series X"

I believe this is the Xbox one version that is compatible on Series X

Because I'm sure the Xbox Series X disc should say "Xbox Series X" and not Xbox One

I have contacted the seller and awaiting a response but thank you for your help

Ok I have both versions of GTA downloaded on my series x the Xbox one version works fine on the series x I then downloaded the series s/x version on the series x I then launched the game and it gives the error message
