So I was able to successfully PC to the Citi Prestige over the phone. A couple of issues arose and I'm hoping someone can clarify things for me.

1. I remember reading somewhere that Citi can expedite a Prestige since it's their Premium card. However, I was told by the rep that it can't be expedited since this is a "new" card. I reminded her that it's not really new since I'm doing a product change. She put me in hold to ask her supervisor. The rep then confirmed what she said earlier and that this is considered a new card and that I'll have to wait for it to be sent by snail mail. So how did people get their Prestige expedited?

2. The rep said it can take up to 51 days for the product change to finish. After the phone call, I went online and I noticed the Prestige is now in my account. I was assigned a new card number with the last 4 digits displayed. There is also a message in the old card indicating that a product change is occurring. My card haven't been shipped yet. So in the mean time, will I be earning points under the Prestige rate for my old card's rate? I had my old Citi card added to Samsung Pay. What happens now if I were to use my phone for payment at a restaurant?

3. Since I got a new account number, how will this affect my Chase 5/24 status? From my perspective, this shouldn't affect things since this isn't a new account. The rep confirmed that my old account history will transfer over. Is this true? I last received a Citi TY SUB in November 2019. Can I apply for another Citi Thank you card like another Prestige and receive a new SUB in November/December 2021?

4. Since I got a new account number, will this reset the clock on my old card on when I'll be eligible for a SUB from that family of cards?

5. If I cancel the conversion between now and the next 51 days, what is the consequence?
