I dont think so. When fully collapsed I have about 10 lists and its even slow when I am trying to expand a list containing 10-15 items. Also, almost entire document is consisting of text, just a handful of photos.
I just updated to the latest iOS 11.2 and it is still extremely slow. I am not talking about a mild inconvenience, I hardly seen any app with such a late response time/lag. It is almost not usable at this point
Anyone who has iPhone 5S, iPad Air, iPad Mini 2&3 can contribute to this as all of these devices has the same A7 processor. I doubt it but maybe there is a problem on my end.
