Cca175-exam not loaded to portal

Hi All,
I was supposed to take my exam today but the exam never got loaded to the portal. I waited for more than an hour and contacted PSI support. They said the exam was going to be rescheduled and I should wait for an email form the proctor.
I checked the portal after 2 hours and the exam was available but the proctor wasn’t present to verify and release the exam
Did any one had similar experience like this?

Thanks
