To upgrade the PNAs you first gotta unequip the PNA you wanna upgrade from every pages that you have it equiped. Then you "save page" and it should let you Upgrade.

The earliest notice i got about KR balances were 4 months ago, so I'm not sure if these are the ones you're looking for, but here's what i have gathered ;

Sorry for 1 large spoiler but that's all i could do, although i don't know when, or even if these changes will be added.
Hope it helps, though!
