"AddDomain" button on Merchant not enable

When I want to create a domain on apple and click ‘AddDomain’ the button is disabled.

I followed all the steps from here -> https://developers.vtex.com/docs/guides/setting-up-merchant-id-in-apple-pay#adding-domains-to-merchant-id

Hello Maria,

Is it the first domain?

Hi, yes it is. Have any problem about this ?

Hello.

I was wondering if the first domain was not validated, so the button could be not available again.
But it´s not the case.

Okay, so do you have any solutions for this case?

Sorry, don´t have it. I would review the previous steps to make sure they were done, like the certificate creation.
