Thanks a lot for the answer. Magically it is working now. I am not sure which magic is doing the trick as I basically tried all the web based tricks you mentioned, i.e., logging in and out to appleid.apple.com and the developer.apple.com website. However, in fact, I was not seeing any new agreement to sign. But I remember that yesterday when doing all this, I was seeing some warning message in my developer account saying some agreement to sign. Though, there was no link for me to click to sign the agreement. So I ended up waiting for a day till this morning when I tried again. Then when I log in the developer.apple.com and I am not seeing the warning message and the notary tool is working. I guess it is probably something to do with the weird caching either with my account or my local browser, no idea. or probably just a matter of waiting a bit. Anyhow, it is working now. I did not try anything on the xcode side, though. Thank you!
