Congratulations! Why would you wanna go for a second attempt when you got the result that you passed? The test result must have gotten registered on their end right?
So I didn't receive any tracker email. I was able to create the account 3 days after receiving AOR. Just plug in your UCI and application number and it will send a code to your registered email id.
Could you tell me what you meant when you said you changed the date and time. Where do you change it? I haven't received my AOR as yet so not sure if it's something mentioned in the AOR or tracker email.
