No, it wants the code sent to the app on the old phone. The app on the new phone is not set up yet, so it will not automatically receive code on it.

If you no longer have access to your old phone, on the verification page, does it offer other options to authenticate, if so, click on it and see if you have set up alternate email or phone number to receive 2FA code instead.

If that still doesn't work, if it is personal account,

If you don’t have access to any of the options listed, select “I don’t have any of these.” This will begin the recovery process. As part of that process, Microsoft will let you add new contact information — but only after a 30-day waiting period.

This 30-day delay is intentional. It’s a security safeguard designed to protect users in case someone else tries to hijack their account by changing recovery info. The wait gives the rightful owner time to notice and stop unauthorized changes.

Unfortunately, this policy cannot be bypassed. You can read more about it directly from Microsoft here:

If it is a work or school account, only your organization's IT department can reset your MFA for you.
