I experience a fairly consistent crash if i read in a text on my iPad if I am using Night Mode. I switch to Night Mode, read, going to various places in the text using several bookmarks. I then use a bookmark to a different text. I attempt to switch off Night Mode, and iOS Accordance crashes. When I restart, I am back in the original text. It seems to occur when switching texts while in Night Mode.
