Auto-save doesn't really save.
On Word for iPad when you hit the back arrow on the top right you have to save or delete the file, why? Normally you can do back and forth to the menu but not on the iPad. If you don't save it, even with auto-save on you lose the doc and can't go back. Auto-save should save it, the auto part of it, but doesn't always.
Auto save on ipad saves automatically. You cannot undo or retrieve history of auto saves saved on ipad. This needs to fixed. I cannot retrieve a history of auto saved items and as a result i have lost documents
