Numbers documents in iCloud impossible to open
Hi!
Since last saturday one of my Numbers documents in iCloud can't be opened. It simply says that the spreadsheet cannot be opened. It doesn't matter if I try to open it on a Mac, iPhone, iPad or iCloud.com. For some reason most of my iWork documents seems to have been opened and re-saved on January 4 at 21:41. The problems began after that. I wasn't even working with iWork then so it seems to have happened "by itself".
How do I get back an older working version of my documents? Since they are in iCloud they are not included in my Time Machine backups. I always thought of iCloud as the most foolproof way to store my documents.
Best regards,
Niklas Johansson
