Express Entry: Change in Living address but not mailing address

[aj211191]

Hi,
I applied for Express Entry in October 2019 and waiting for COPR. When I applied, I had different living and mailing addresses.

I am planning to move from my current address to a different location, but my mailing address will not change. Do I have to notify CIC of that change, even though my mailing address remains the same? And if yes, is web form the way to do it?

Thanks for your help!
