I faced the same issue and solved it by switching to the correct directory.

You can do this by clicking the profile button in the top-right corner and selecting 'Switch directory.' After switching directories, you will still need to switch accounts by clicking the 'Accounts' tab, which is located between the 'Create Unlimited Account' button and the notification button.

However, I still face a login issue on the API portal, where it says the same email has been used for two or more users.
