Hi
I understand. I was also in the same situation last year. At that time, it was a unique situation and I did not have any reference because most of them were receiving 4 point, 7 point emails or remedicals or ALs. Now, people are receiving "Do you want to immigrate email" along with remedical or pcc or passport submission.
I really wish you don't have to go through the hassle of submitting new PCCs again. Everyones case is different. For me they asked me to submit updated ones and may be in your case they won't. Things would have changed this year. You never know
I had sent my queries to the RROC email and they replied the very next day. Maybe you should try the same. They had also told me that if you have issues submitting documents online, we can email the same to them.
So, don't worry it will all be fine. If you want submit the old PCC along with the new PCC(currently residing) and mention a note too.
