Об отсрочке говорится в самом Affidavit:

In case that, exclusively for legal reason, the Tax Authorities of myresidence country cannot provide with the certificate in such period, I will provide Freepik with sufficient evidence ofthis issue and I will provide the document within 30 days of becoming available. So for example, I the authorities willissue the document from July 2021, I will provide this document by 31 August 2021
Отсрочка 30 дней с момента получения данной справки, а не с марта.
