you can reply to the original email right away requesting the correction to your ecopr (the email shouldve said, please check the info and let us know if any correciton is needed. otherwise sign if correct).Good news, I have received ecopr yesterday, got credential email on Tuesday night a d logged in and updated photos for me and family. Then they sent ecopr on Wednesday Sep 29, also status in account is updated as Approved,. Unfortunately, they wrongly mentioned my Original Entry date to Canada, not sure on how much it may affect, it won't affect my eligibility or points though. When I looked process for correcting copr, it is only by sending post with form 1436 e with all proofs.
I will update you all once I receive PR card.

Need to correct original entry date on ecopr
original entry date is actually a bit important as it helps count for when you can apply for citizenship (if you want to count some time as temporary resident). although it may not matter eventually
