Are you seeing ERROR_VUE_WIDE_BLOCK in the URL when you try and schedule the exam?

ERROR_VUE_WIDE_BLOCK is typically because your account has been blocked by Pearson Vue which normally happens because of multiple failed payments. You need to contact Pearson Vue support using the link on https://aka.ms/CertificationSupport to get the block lifted.
