I have 3 dependents and I was able to link myself and 2 of my 3 dependents but the 3rd is not linking and I used the same principle that i used for me and the the 2 that linked. Go figure?!?!I am thinking that when it does not link maybe IRCC did not enter the information on their side and when you enter so many parameters such as UCI, name, date of PR etc their system must use a protocol of matching most of the information rather than 100% exact. With that being said when the information is entered by IRCC in their database then coincidentally that it was at that time you tried it then it matched. @legalfalcon what do you think?
