Thank you for letting me know! Fingers crossed!Don't worry just yet. i checked my PR portal and it's also "submitted". maybe they are still working on your case.
when you link your application, for the number of persons in the application, it should be sponsor+co-signer+PA+all PA's dependants. do not include children in the sponsor's family.
Regarding the total number of application, I thought we have to count our kid too. Did I inflate the total members of my household?
