Your Twitter Developer account will soon be deactivated

Hi Korean, The Twitter account associated with your Developer account has been deactivated. This will prevent you from accessing the Developer Portal and your client apps. Any integrations with our APIs available on Developer.Twitter.Com will also be erased. If you have paid product subscriptions, they will be set to Sandbox (free) at your next renewal date. In addition, your payment information has been removed from our system. IMPORTANT: You are the last Admin on this account. Your account will soon be deactivated if you don’t take any action. If you want to select a new Admin, please reactivate your Twitter account, then go to the Developer Portal. In the team section, you can select a new Admin for this account. The new Admin will then be able to adjust product subscriptions, billing information, and client app integrations . We are sorry to see you go! The Twitter Dev team
