On the one hand, it's autosave is unreliable and may not save your progress. On the other hand, it can delete big chunks of previous progress by not fully loading it before a forced manual save! Not to mention said forced manual save requires Save A Copy trickery to pull off. It's very shameful that a ten-year-old document app on an equally-old tablet is more effecient than this. No one cares about making quality, stable apps anymore...
