numbers on iCloud is INCONSISTANT
The "UNDO" fuction sometimes appears as I progress through my work, then when I really need to correct (or undo), I can't find the undo buttom (othewise known as command/z on our macs. This proves very frustratrating and difficut to use because of happazrd inconsistency with the ios numbers program. Where is the undo fuction/key in ios numbers. Thanks for you guidance
