your declaration will remain submitted and since they have approved your address I am pretty sure that they have prepared your PR Card and mailed it to your address already and regarding the Photo, bro I received my Card almost 2.5 months ago and they are still reviewing my Picture, seems like have never seen an alien like me
I hope they at least approve my photo before the end of 2025. Regarding emails nope they don't send you any emails after ECOPR although I think you can check if your PR Card is mailed or not in GCKey, in my case my representative submitted my application through his GCKey so he only had access to it.
