Facing difficulty to changing student ambassador registration display name

For Microsoft Learn and Applied Skills, the displayed name can be changed in the Learn profile settings:

1. Select the profile icon in the top-right corner.
2. Select Settings.
3. Under Personal info, username, and URL, update the Display Name.
4. Select Save.

The Display Name is the name shown on the public profile, certificates, and transcripts.

If the name that needs to be changed is the Legal Name used for certification identity verification, that is also managed in Learn profile settings. If an exam is already booked, changing the legal name requires Microsoft support approval.

For a Microsoft account display name on Windows or Microsoft account services, sign in to the Microsoft account and select Edit name, then Save. Name changes can take up to 24 hours to update everywhere.

The provided context does not confirm whether changing the name affects the Microsoft Ambassador application process.
