Hello! I'm Jen, and I'd be happy to help you out with this issue.

I'm sorry to hear you're experiencing this issue. May I know where you encountered this error message? Does it appear when you try to access the Microsoft Rewards website? Looking forward to hearing from you. Thanks.

Kind Regards,
Jen :)

Yes, every time i try to access the rewards

It's working for me now --- no changes on my end --- but thanks for the link. I'm sure it will come in handy in the near future.

Same issue, Microsoft start not showing rewards, if you search from the Microsoft start page, it bring up Microsoft Bing search engine and results. This page shows rewards but when you click on the rewards, this message comes up:

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

it's worked with me in google but not in edge
