No response to account recovery request by expected date

I suspect the Account Recovery request was cancelled automatically due to one of these conditions listed in the Support Article.

• Regardless of how you started the account recovery request, you should turn off all other devices that are currently signed in with your Apple Account until account recovery is complete. If your Apple Account is in use during your request, your account recovery will be cancelled automatically.
• If you started your account recovery request with iforgot.apple.com through your device’s browser, you should avoid using that device during this period. If possible, turn that device off. Using that device might cancel account recovery.

Also in that Support Article, it says if you do not receive the text message/phone call on the expected date, you can check at the recover link provided. This would assume it has not been cancelled as above.

• When the waiting period is over, Apple will send you a text or automated phone call with instructions to regain access to your account. If you don’t receive the text or call, once the period specified in the original email is over, you can still go directly to apple.com/recover.
