Problems getting Numbers file back from iCloud
We are using iPads to do some field work. We created several spreadsheets in excel and then opened them on my iMac (at home) in Numbers. We then setup iCloud accounts for 12 iPads and populated the clouds with the files. Once we were on site, we'd enter information into the numbers files.
Now that everyone is back in the office, some (not all) of the Numbers files on iCloud won't download, print or email as anything (Numbers File, Excel File, PDF).
Has anyone experienced anything like this? What did you do if you did?
