The AB-730 exam is still in beta. You are told this when you start and finish the exam that your result will not be available immediately

If you’ve taken a beta exam, you’ll receive your score about 10 days after the exam becomes available worldwide or “goes live” -- approximately 10-12 weeks after the beta period begins. This time reflects a comprehensive process including statistically analyzing results and data, evaluating the performance of each question and reading and evaluating all comments provided during the beta exam. As a result, you may not receive a score for 14 weeks depending on when in the beta process you took the exam. Please note that the beta exam process and the time it takes to receive your results may vary.
The exam is due to go live at the end of this month, so your result will be available mid-February.
In future, if you want your results straight away, do not take a beta exam and wait for it to go live.
