Thank you for your tip! Now I do have a piece of mind.
I would like to share my experience.
I applied for PR personally with my telephone number. Later my company applied extension of my work permit via an attorney. Soon after that IRCC evaluated my eligibility and marked it as passed. Due to some reason, IRCC updated my contact information in my PR application with that of the attorney referring to the WP application. I learned this from the GCMS notes applied.
Right now, I'm submitting a web form to update my contact details back. I'm also following up with the company attorney to handle the call that they might receive from IRCC in connection to my PR application.
I hope this may help somebody who is on the same boat.
