Why does my Xbox series S said something went wrong when I press Microsoft Store app then I...

I just checked it out on my Series X and it's the same for me.

I'll use the "Report a problem" app to report it to MS, cos there's nothing we can do to fix it at our end.

On XBOX Series X the Microsoft Rewards app hangs and when it does open minutes later, and you click on the weekly it gives an "oops, looks like something went wrong service unavailable" error with only an exit

I’ve used the hard drives for my Xbox one but when I bought the hard drive, it said it was compatible for the series s.

The game I bought in the Microsoft store on the Xbox one. I was trying to play it on my series s.

thanks for the reply but its not letting me sign in on the Microsoft store, Xbox app and the companion app. when i press the sign in button on Microsoft store nothing happens and on the xbox app and companion app, i press sign in to xbox live and for a split second something try's to load but instantly closes itself. as i said I've tried repairing uninstalling but it still wont work.
