on my MS Rewards account today, for the first time, I got this message: We're unable to complete your request invalid_request: The provided value for the input parameter 'redirect_uri' is not valid. The expected value is a URI which matches a redirect URI registered for this client application. I access this when I access MS Rewards on my FF home page: https://login.live.com/oauth20_authorize.srf?client_id=9c941f7c-a811-4e9c-8e66-29fdec50490f&scope=openid+profile+offline_access&redirect_uri=https%3a%2f%2fsnr.wus2.binguxlivesite.net%2fsignin-oidc&response_type=code&state=CfDJ8I2_1MsyeC5LgSUu2RHmXGM8NYR9tb3xmjMlREe6oQOjEfzHFEUWpw30cqkq771pzVIhypEtFqCBc5D-UODbjDQRDt7Ne1SEKfgdy46mi-No0Lg0fPe82eRxVHtS7bTdLxGl2cFchPkU66mIpnlY5isc9n0UqhWZ5NxF6a7Ikx_gpbi1EQIjk0MVXkVeq07WCNQe0p_C8ViFNBwjRIatZg245flkXtpHjlb1dPOoD1Rjd2guTfssPycFD5BeY4r-re6dmCzvZjvWH6joR2_GsNYKKlrRJQpi7DqCBdN2RqfRck6CqndCQAp0r_iYrDaOXb-ogUmUtv-BpbCu0f1So864MlUseJDGHRpvzQDe02ETlzmMmPM2QNLzYfJGii9n7jtEr9R_J_TX6NRAN93B64pA3N90YkVJ6eyK8weAOu9AIA6lbFvJ_mnfxICEEJFwhYByHH77g6hpQTOS5Tz97Kfm4Ycx0fCAA8p9BmdmnKa9-v0r-qa9D1Z-njY7BxdbQbtqWSz18Cg5FAs2EVZn8XQ&response_mode=form_post&nonce=638426827054027297.YzNjNmY1OGYtZDY0NC00YjlmLWE5OWEtZGVkYzRiYTBlYzdjN2YwYjNmMDItZDg4ZC00OTA3LTkzYmUtZTVhYmRlYWQ2NTBk&code_challenge=3yhQGg2lh3Cap_R7IDWk9-ouGYj2g3jJfujMzb3fkcw&code_challenge_method=S256&x-client-SKU=ID_NET6_0&x-client-Ver=6.23.1.0&uaid=43313cd0afae45969ebf5c46ef8d7e8d&msproxy=1&issuer=mso&tenant=consumers&ui_locales=en-US&client_info=1&epct=PAQABAAEAAAAmoFfGtYxvRrNriQdPKIZ-XC3bCyPcKLOzsZYRz6lpczJgwm6PlBpJSPyYzGTCentiNRAqqk3_W8VOgCNQVatmpG9RQvuUH4zmTt7_Iex1K6tMApLev5-gKu0UFiETGIm6xLIFOKDEtcYtFaDmIsqso_qaav6O9zUu71PdhRB8IGY8O5SdMJ5v8kG0kIZCvvYOX9A5kug5vobSGMuCqifBCEDo_7A4IUgSls89mKZptyAA&jshs=0&fl=easi2&cobrandid=03c8bbb5-2dff-4721-8261-a4ccff24c81a&lw=1#
