This seems to be a common issue with VO Montreal these days. When I replied to portal 1 on July 9, then I got back an automated reply, but when I replied back to the second notice of portal 1 on 26 July then no auto reply was received. From the forum, I got to know many were not able to get the automated reply from 26 July onwards. May be they have changed their system settings!! No need to worry. Some ircc agents told that it was a must to receive the auto reply, whereas some were of the view that it was not a big deal.Hey, did you receive an automatic revert after replying to Portal1?
