I thought I was one of the lucky people that got the Costco one year unlimited plan a little over a year ago. As movie pass started putting limits to three movies on existing clients, and even converted their own annual plan into a monthly 3 movie plan, it seems they weren't able to figure out a way to convert Costco plans, so technically I'm still on the unlimited plan.
However, since August, it has been not only a pain and much more restricted in terms of movies, but very frustrating. I live in NYC metro area, and rarely find a theater on weekends that has showtimes available. A couple of times the app will have showtimes available, but as soon as I get to the theater, all the showtimes disappear. So now not only do I not get to use movie pass, but also I've already wasted Time and money to get to the theater. I end up buying a full price ticket since I'm already there.
Recently they pushed an app update which made the billing section inaccessible, unless they fix it, you won't be able to cancel your subscription.
Not a fan!
