Hi Fey, Celine from the Community Support team at Figma here! I was able to see your support case and flagged internally for visibility. I can also see that our Support team has been working with you and that you've found a resolution!
From what I can see, the team is helping you move your seat to the correct team, and update your billing setup to match your intended configuration.
If you have any additional questions, please continue the conversation directly through your existing support case, as the team will be best equipped to assist with your account and billing details. I’ve gone ahead and marked as solved here, thanks!
