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 sounds like it is merely an issue on their end. I haven't used the platform in a while but got it up and running. I was hoping to utilize the Spotify offer I got an email about. Alas, hopefully sometime soon they will put together a solution. I am just going to keep trying back each day and see what happens.

I am having the same issue trying to get to Microsoft rewards. input parameter redirect_uri is not valid. we are unable to complete your request. Support so far has been useless, transferring me to 3 different people and a link that did not work just directed me to the same error message. Please, this is frustrating, I need an answer.

I was able to get to the full rewards page in Chrome (I have windows) and submit a request for help from Microsoft rewards support just today. This does seem to be an Edge problem, but I don't want to switch browsers as I prefer Edge, and I don't want to go back and forth between browsers. Hopeful they will reply.

I also have this message when I try to open it, if I go to the microsoft rewards website it looks normal, but if i click "log in" it comes with that message, same goes with "registration".

I am also getting this message when trying to click through the apps link to Microsoft Rewards. I can access my points by going through Bing and clicking my points to have a drop-down menu come up.

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 :)

I'm also getting this error today.
