Performance very bad on iPad app
We're a team of designers and developers and I'm using XD as it's super speedy, works across platforms, and the prototyping performs really damn well.
One of the major frustrations is how long it takes to open documents on the XD iPad app.
I'm working in a 23MB XD file, and opening it on an iPad (the version released in 2017) easily takes 3-4 minutes. We have 6 iPads and a few iPhones, and it's the same on all of them.
I'm not sure if it's your servers, or if it's the app, but this performance is unbelievably slow. The rest of XD is super fast & lightweight, but the iOS app is a whole different story.
