I am not able to log in to my Xbox series S

Note* I am currently playing on a Xbox One S and I am switching to my Series S in a few weeks. Will I be able to download the game automatically onto my Series S or will I have to pay for the game again ?

So so long as I long into the Xbox Series S/X with my account, the one I use to buy the game, I download the game onto the console? I’m just making sure because the Xbox series S belongs to somebody else in my house hold, but I’m still able to use it even though it’s not mine. I was just trying to see if I logged into the series S with my account I could just download the game on there and then play it from there.

I would also like to ask a second question, which might nulify my first question.

Is the situation I present below possible?

We own the ultimate edition of FH4 on my account.

We have 3 xboxes (2x series s and 1x one s)

Home console Series S: Wife logs in and plays Forza Horizon 4

2nd Series S: I log in and play FH4

Xbox one S: I log in to give acces to my daughther, and she logs in on her account at the same time to play FH4 on her account.

ALL AT THE SAME TIME.

Just wondering if that is possible and/or allowed.

I am considering purchasing the new Series X. Before I do I want to know if it is compatible with other Xbox’s when playing Gta 5 Online.

For example, my cousin plays on the Xbox one s and my brother plays on the original Xbox one. Will I be able to play online with them?

Short answer, Yes.

Xbox One,

Xbox One S,

Xbox One X,

Xbox Series S,

Xbox Series X,

They will all be able to play the same games online together, no matter who's on which of these consoles.

Hi

Let me explain a little further please..

I have an Xbox one S, my son had and Xbox one S, on this set up his Xbox was my home and mine his, and I could share my ultimate game pass with him and we could game together with zero issue (he has no subscriptions just me, and I did not need to be logged in on either console for him to access any game)

Now he has a series S, which is set as my home, and my one is is still set to his home, only now he only has access to everything on the series S, if he logs into my one S I need to be logged in, and worse still if he’s playing on the series S (without me logged in) and I log in on the one S, it tells me I’m currently playing on the series S and if I terminate the session, it kicks him off - we can no longer play the same game together.
