Good evening guys. My passport was returned today. This is to help anyone who would've this challenge. I got my ppr on 9th May. However, I had renewed my passport and got the copy on 10th May. I asked
@marty90 what to do and he directed me to either submit my new passport with a short explanation letter or cancel my old passport and submit the new one alone. I decided to do both. But I first sent a scanned copy of my new passport and the cancelled one (data pages) through an email and finally submitted both two days after. I added the short explanation letter too. Everything worked out fine. All the best.
