Well, the interview date is in the past and this is likely due to a glitch that's been happening with their systems for about 3 weeks now. Don't worry, if you did not receive an email, it is most likely a glitch and no action is needed from your end.In the online tracker, i got information this information :
Interview required
You've been scheduled to attend an interview with our official on June 23, 2021. Information and instructions will be sent to you"
But I am yet to receive any information in my email. Did anyone have similar experience?
For your own peace of mind, you could call IRCC tomorrow at 8 AM local time and clarify this with them.
Good luck!
