Can't publish my first widget: "We detected a change to your account details"

Hi Figma team, I'm trying to publish my first FigJam widget, (widget ID 1701374835505134746), but the publish dialog shows: "We detected a change to your account details. Please contact support@figma.com to proceed."

The only account change was enabling two-factor authentication yesterday (8 Nov), because the publish dialog required it. I emailed support@figma.com on 8 Nov and haven't received a reply yet.

Could someone please verify my account and lift the restriction, or nudge my request to the right team? Thank you! Yana
