Question on how to refresh the Home Screen on my Series S

To refresh the home screen, you can simply press on the Xbox button; then highlight home, press on the menu button. Then press on Refresh

You can check this if you don't know the button's name Get to know your Xbox Series X|S Wireless Controller | Xbox Support

go to home screen press LT+RT+Y this refreshes the screen.

On your home screen is the friends tab showing if no press RT+LT+Y at the same time this refreshes the home screen.

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.

press LT+RT+Y that will refresh your home screen,
