I'm not sure. I didn't use the Portal for myself as I'm already a Canadian Citizen, so the Portal account was entirely for my wife's application when we submitted it last year.Your might be unique since you already used the portal for yours and you did make use of same portal for your wife, possibly there was issues with that.
I had heard cases where there was delay with people's P2 due to the fact they had an existing portal and ircc was trying to create a new one for them. It was until ircc was notified that they had an existing portal, that was when they now updated the old portal with the P2 information.
