I have changed the e-mail address of Silicon Labs account nearly half an hour ago. But I am still able to log in with my older e-mail address. I can see the my new e-mail in my profile. Need much more time to update the login system with my new e-mail address?
I am not sure where you updated your email address. If you can send me a request via email (email@example.com), I can update your existing email with the new one for you.
