Same here, no charge. Just the ID photos. But it took longer to have it in the mail as I expected.
Every time your passport expires, you need to get a new card. It's actually dumb, they shouldn't put your passport number in print on your card, just make a chip-card, this way they don't need to replace it. And in fact the APRC is a goldmine for ID theft, everything needed is printed on the front of the card, lots of stuff not needing to be there.
I actually signed up for the Digital Citizen Card while applying for the new APRC, but the whole application thing is a mystery. Never got the card.
