I did my online test in last week and passed it with a pretty high mark. I recently got an email saying that they "were unable to accept the test due to technical issues" please guide me what would be the next steps from the department.
In the other thread, you mendioned that the email you've received has instructions: IRCC will provide you with a new test invitation that will explain next steps. We are unable to provide a timeline for the next test notice, so please
continue to monitor your email.
Monitor your email - This is what you should do.
Wait patiently at this point. It should lead you the best way. Fingers crossed!
P.S.
I think you don't need to do multipositing. I made the same mystake when I was a newbie because I was unsure every person can see every thread, but I can now shareing this information: Experts are checking all threads and give suggestions and advises accordingly.
