The latest iOS update seems to have messed with the Reading List function. I can no longer figure out how to add pages to my reading list or enter reading mode for articles.

Pages already in my reading list will open in reading mode and still have the “add to reading list” icon available, but if I exit reading mode I lose the ability to add it to my reading list or go back into reading mode. I also cannot enter reading mode or add new pages to my reading list from any new pages.
