Virgo,
Take photos conforming to new specs, also print photos with date stamped by photographer on the back, not hand written. Try multiple times since some offiers may not consider your request.
My experience, PR card processed when landed but new photo was not accepted; tried to submit new photos next day but was refused; tried again in the following day and photo got accepted but was informed by the officer that date should be stamped by photographer instead of hand written. Hope it still works.
I saw there is a photo shop right across Harry Hays building, maybe they know everything.
Hope this helps.
