Go City: New York Explorer Pass

Can you please point outwhere those instruction about downloading and app were? I have read and understood that most require bookings and I have used pass on my first attraction where I made a booking there and then with no issues. Only second attraction that I struggle with. I searched on your website for those instructions on downloading the app and I couldn't find them. I also spend few hours whilst was on holiday to try and find how to book for cruise and still couldn't find. Not even in FAQs. I messaged your customer service and asked the same question only to get am acknowledgement few hours later when I was out and conversation was closed immediately saying that due to me not responding to your 'hello' chat was closed. I have tried my best to find out but clearly not successful and your website didn't provide me that information. You need to make it very clear and easy to find that the app needs to be downloaded and pass should be registered on the app.
