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 contacted Microsoft through chat. They gave me a link to contact bing rewards customer support that gave me the same message. They told me to open an inprivate browser (you do this by clicking on the three ... at the top right of your browser) and when I did that, it let me get to the link they provided. I've sent them a message and it created a support ticket. I did find that by using the inprivate browser that I can get on my bing rewards dashboard. Hopefully, they'll get back to me, but I'm not holding my breath.

This is the link they gave me to contact bing rewards support. Hope this helps others. https://support.microsoft.com/en-us/supportrequestform/cf50b787-a987-a7ff-133c-6c4e3f638013

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.

Yup this is since last update. I have the same. I may untrack Bing if this does not get fixed. Happens when using Rewards which is the only reason you would allow Bing anything...
