Can you please share your timeline? I also updated IRCC about non-accompanying spouse, but they ask me to pay application fee for spouse and her fingerprints/medical. Nothing happened after..it has been 9 months since I receive my Portal 1.
I'm in very similar situation, added my spouse in mid july after P1 and received P2 in August that contains only my information.
Nothing after that.. totally silent.
Please update if you have information about this situation.
