I changed my Microsoft password and now I can't access the game streaming app.

Did as you suggested and the purchases are shown. The only change I've made was a week ago I had to change my password due to Microsoft not suddenly recognising my account. The only game I want that I can't access is forza 4

Errrmmm when I access different devices, and the email account apps within the account is the same but to access various apps I would have to go into the settings of all these and change passwords. The device access on these are by different methods but
apps within will require change.

If I change the Microsoft ID password then all these need updated. Great if there’s a security issue, but not so great since the problem is due to a major failing in a piece of Microsoft software. Chat with “expert” led to the usual uninstall and reinstall,
remove app data etc ..... none of which worked. Ho hum.

Fortunately the failing only gives him access to my Xbox Live profile and nothing else.

I would think changing the password to gamer account and any of the streaming apps that require passwords would stop this issue.

The email and password is 100% correct. If i was typing it in wrong i wouldn't be able to sign in here to post about the issue. Microsoft has made is that way as there is only one email and password used to login for all their services. I believe the problem
is either a windows 10 issue or because i had to change my alt email for getting codes sent to me. So i now have a 30 day wait period on my account for the change to take place. Either way i can't get access to the xbox app on windows 10 or GFWL still so i
am unable to install any of my games untill i can login. i hope this is fixed soon.

I have tried all of the above, including clearing cash, using app password, 7sung Microsoft password, changing password, recurring billing is already on, I even did the initial setup again, kids profiles work 3xceot they won't download any game pass games because it says it needs my account...I'm at a loss can't figure it out for the life of me....
