Hey @jonnyrnixon, thanks! What didn’t work with Playstation and Amex specifically? It might be they don’t yet have our card details in their databases - some merchants take a long time to update them 
Bill splitting is definitely on the roadmap! It would be so great to be able to quickly split a bill with friends (a la Uber) and they can pay with a couple of taps. We want to get P2P payments out the door first though (coming soon!)
Thanks! Please keep the ideas and feedback coming - it’s so helpful
