Why was there even pressure to deliver if the official API wasn’t even out yet? I thought they were just working on UI and basic functionality until they can plug in the API, so if anything they had more time and leisure than if everyone were screaming “i need it now”. It seems more likely they just bit more than they could chew and decided to give up the app development since it ended up being harder than they thought (and that’s completely fine to do). You don’t really make an app like this overnight, especially if you have no prior experience doing it.
