Do you know which office your invite came from? Although it does take some time for them to update you may want to give IRCC a call. The reason I say you may want to call is because sometimes your photo/ID maybe blurry and they trigger a request to send them clear photo but for some unknown reason that request doesn't make it to your inbox.
Also, I am not an expert just a regular member so please do what you think is best for you.
Thanks. The test invite said West Canada. So thinking, its Vancouver.
