Hi.I did once after receiving the test invite. The instruction are in email, what to do if you are unable to give the test. I just sent an email(provide in invite email) that I am currently not in Canada and will be back in 2 months. and IRCC sent me another invitation after two months when I was back in Canada
Do not try to do the test outside of Canada. IRCC/CBSA have records when you enter or exit Canada.
Out of curiosity, did they send the second invitation exactly after two months or did it take a long time after you were back?
I’ve asked to be rescheduled as well and they said that they will reschedule me after Mid-August 2021. It won’t be nice to wait another year to get the new invite.
Cheers.
