Buying L2 after beta

I participated in the beta so I had free L2 clearance when the game went live and understood it would reset to L1. It took a few days, but I just noticed today that I'm back to L1 and I want to support you through buying L2, but the game won't let me. When I'm on the account screen in game, I can't figure out how to buy L2 clearance. It's entirely possible I'm missing something and this isn't a bug, but I've tried tapping on different areas of the L1 badge and nothing happens and there's nothing else that looks like it would take me to the purchase option.
Thanks! Love the game.
