Good day, thanks for your question. Kindly refer to the below for the other things that you can check.
> Ensure that you are really not using or connecting to VPN or proxy.
> Logout and login to your account.
> Check and try the dashboard on a browser if you are using the app.
I would also suggest to monitor it for a bit more of time as there might be an issue on the system or server that is interfering with this one but if it will still be the same later today or tomorrow then you can head over to the link below to check it directly with the MS Rewards Support as they have information and access to provide on what transpired on the issue that you have encountered.
