I've been adding credit cards/debit cards to Apple Pay -- so far the process is pretty easy. However, I've noticed the following odd things: 1) Barclay card won't activate. It says that they're not using Apple Pay. Barclay card is what Apple uses for their 0% financing, etc.. Very strange. 2) After inputting 8 cards, that seems to be the limit. I can't enter more than that. The option to add more is greyed out. 3) Wells Fargo is slow, and requires an app. 4) Bank of America requires a phone call. 5) Amex is super fast -- text message is all that's needed. 6) Citi does an automated call or text message. Pretty quick. Anyone else noticed anything else?
