I'm trying to purchase my first theme (still under the 3 month trial). It takes me to Add A Credit Card to purchase the theme since I haven't linked any payment method to my account. When I click on add credit card it just sits there loading, and it never loads. I see a little blue bar along the header slowly inching across my screen, but I sat there for ten minutes and it never loaded. This is seriously hindering my ability to build out the store.
