Cannot sign into the Xbox App. How can I sign back in?

is the mobile app, or on the pc?

Hello Devon,

Thank you for posting here on the Xbox forums. Can you verify that your Date & time setting is set to "set time automatically"? Select the
Start button > Settings icon >
Time & language. Check the app again afterwards if you had to update this setting.

If that didn't work, select the Start button > Settings
icon > Accounts, then find the Microsoft account you used to sign in to the Xbox app and select
Remove. Then go back to the Xbox app and sign in with the Microsoft account you just removed. Make sure you know your sign in credentials beforehand. Let us know the results!

Hello Devon,

We're glad that the information provided by XBF Chris was helpful.

The sweepstakes contain rules that can be found at our Microsoft Rewards promos website. Try checking the rules out there and let us
know if this is helpful.

Best wishes!

Thank you! I also want to ask how does the Sweepstakes work?

Try restarting the Xbox app if on windows use task manager (ctrl + alt+ delete) to close it.
