I am unable to register for AZ-900 with Pearson VUE


I'm attempting to book AZ-900 through Pearson VUE. When I follow the link from https://learn.microsoft.com/en-us/learn/certifications/exams/az-900 after picking United Kingdom, when I arrive at https://examregistration.microsoft.com/ there is a Please hold... message which never goes away. In the browser's console I receive this error message

I have tried Chrome and Edge (Chromium) on MacOS X Big Sur, along with Chrome on Windows 10. On my iPhone (Safari) I see a message which states "We can't access your profile to schedule your exam". I've tried hard refreshes and InPrivate browsing but to no avail. I reached out to Pearson VUE and they have asked me to ask here.

Thank you,

    Microsoft Certification / Training is supported on their own forums. I'd try asking for help with exam scheduling / vouchers in dedicated forums here. (Participate\Ask A Question)
    Exams/Exam Registration/General Registration Questions
    Exams /Exam Registration and Scheduling/Scheduling with Pearson Vue
    Exams / Discounts/Vouchers/Special Offers / Event Offers
