I am trying to book an at home GRE. But I am unable to select any time zone. Basically it shows multiple days where seats are available but when I select any date they show no time slots available. I called the official website and they told me to wait for 7-10 business days and send them an email.

Just wanted to know if anyone faced the same issue before? I am based in Singapore.

EDIT- Seems like ETS resolved the issue on it's own. You can book tests. All the best to everyone giving their GRE.
