file lost after a numbers crash
Hi All,
i was working on the plane on a document. I briefly saw a flag saying numbers cannot save to the cloud or such and then numbers did crash. The file seems to have been totally erased. It is not in the recent document, nor is it on the icloud space or on a hard drive.
As i had been storing datas for 6 months, it is a significant loss. Can i do something to retrieve that file ?
thanks for your help
