Thanks for your suggestion. I am really greatful for your quick answer on LinkedIN as well, but I have some doubts because the PPR email asks for photos if I have not filed a paper based application. I have asked some clarification from Vienna VO but they have not responded yet...
I have got this letter from VO, the highlighted part was marked by the officer originally:
Depending if you already provided photographs or where you submitted your application, you may have to submitT photos.
a) You have to submit photos if:
o You submitted your application online (such as under Express Entry)
o You submitted a physical paper application to one of the Case Processing Centres in Canada (in Sydney, Nova Scotia, in Ottawa or Mississauga, Ontario) and your file was primarily processed there or it was transferred for processing at any other IRCC offices worldwide other than the Embassy of Canada in Vienna.
o You submitted a physical paper file application which was transferred and processed primarily at the Embassy of Canada in Vienna, without photos or with photos of incorrect specifications or with photos older than 12 months.
b) You may not need to submit photos if you submitted a physical paper application less than 12 months ago with passport-sized photographs matching the requirements above to one of the Case Processing Centres (CPC) in Canada (Centralized Intake Office in Sydney, Nova Scotia, CPC-Ottawa, CPC-Mississauga) and you were informed that your file had been transferred for processing to the Embassy of Canada in Vienna.
