Spoke to an IRCC agent, sharing what they said for reference to others in the same situation:
1) Since the date mentioned is Nov-10, expect an email invitation with the details and options by Oct 30-31, 2025.
2) Nov-10 date with no email invitation is still tentative; So, the Agent took the dates that we are not available for Oath to update in the file. This will help/inform the officer to select a new event date accordingly.
On a side note: I have also raised a web form for the same.
Hope to see the revised date soon.
