Hello.
It depends, if you are on Ecas and you see DM on sponsorship, that means Sponsor has been approved (SA) if you see DM on Permanent Residence that means your process is done and you're just waiting for a landing letter, that's basically what every thread here has mentioned, seems to be truthful.
Yes, I got DM on both side last week, since then no update at all.
Feb 4 2019- AIP & SA
Feb 5 2019- DM on both side.
