The correct order
is definitely DM first, upon completion of background/security checks, eligibility etc.., CIC will make a
decision on PR application, whether it's positive or negative. When approved only then PPR or CoPR will follow, technically and logically that is definitely the correct order.
Now
Ecas indeed does NOT always show the latest updates on application progress, that is true. Some people wait for their AOR and then suddenly get surprise SA for example. Some people know they've been approved SA (by phone) and then spend 2 weeks waiting for any online update (file transfer or SA email). Regardless of the VO (Manila or not) Ecas is notoriously unreliable, however in general the correct order of things remains the same and PPR will not happen unless
decision has already been made first, whether eCas shows it or not ;D
Best of luck and fast processing to everyone, let's all hope for that DM soon
