I was buying Gems today with my card and it let me hit next but then it pulled me up to the “review your order” page and it would not let me hit confirm.
I’m having this same issue. Is there a fix I can do on my end? Or is this a game bug that I just happen to run into?
EDIT:
I relogged a few times, restarted the client, it eventually worked. I don’t know what fixed it.
