The method was working fine before the update but now its not working and i cant develop. You can replicate the issue by creating aws account and adding an user pool. I have created a standalone app too to confirm the problem.
Environment: Windows 10, Xamarin forms app(.net shared)
For reference: "https://aws.amazon.com/blogs/developer/cognitoauthentication-extension-library-developer-preview/"
Please help as it is blocking the work for more than 3 days now.
