NUMBERS didn't save my work - why?
Hi, I updated a Numbers spreadsheet yesterday and hit save before closing it (although I'm pretty sure this step isn't necessary) and when I returned to the spreadsheet 30 minutes later the changes had disappeared. Luckily I hadn't made too many changes on this occasion, but this could be devastating and now I don't trust NUMBERS. Has anyone else had this problem?
Maybe it was offline and couldn't save to iCloud? Why has this happened & how can I recover my changes (if possible)?
I'm using an iMac (late 2015) running Big Sur 11.7 and saving Numbers to iCloud. I have logged in to iCloud and the spreadsheet is also lacking the changes there.
Please help.
