What actually got easier for you once your ARC number finally linked everywhere?
I feel like this is one of those Korea setup things nobody explains clearly until you're already stuck in it. I'm trying to figure out which parts of daily life really changed for people after the ARC number started working properly across phone, bank, delivery, verification apps, etc. If you had to survive the awkward in-between stage first, what was blocked for you and what suddenly started working after the linkage finally went through?
