I have a desktop application using MS Graph SDK that asks users to authorize access to their OneDrive accounts, using OAuth. It has worked fine for months, but starting today users are getting an error the first time they are asked to give permissions to my app. The error doesn't show if the account has previously given access to the app.
You can reproduce it trying to sign in in the OneDrive sample app: https://github.com/OneDrive/onedrive-sample-apibrowser-dotnet
I attach a screenshot of the error (in spanish):
