New individual developer onboarding stuck at "Profile details" — Continue button does nothing (all fields verified)

I'm trying to open a free Individual developer account through the new onboarding flow at storedeveloper.microsoft.com. I completed identity verification (government ID + selfie), but I'm stuck at the "Profile details" step and cannot continue.

Details:

• Microsoft account: ******@outlook.com
• Account type: Individual developer (free / zero registration fee)
• Country: China
• Postal code: 276800

What I see:

• All fields show verified: email "Validated", phone "Valid phone number", address "Address verified"
• No error messages or red marks anywhere on the page
• The Continue button is visually enabled, but clicking it does nothing — I cannot move to the next step (in some attempts it stays grey/unclickable)

What I already tried:

• Different browsers (Edge, Chrome), InPrivate/incognito windows
• Clearing cache and cookies
• Waiting 5+ minutes and refreshing
• Restarting the whole flow from storedeveloper.microsoft.com

It looks like the known issue where the onboarding flow loses its binding on the backend (see similar reports in this forum from March–July 2026).

Could Microsoft please check my account and re-bind / hard-reset the step 3 (Profile details) flow for this account?

I can provide a screenshot of the page if needed.

Thanks!
