I'm having trouble opening a numbers spreadsheet I created spreadsheet 2 weeks ago on my iPad. Up until today it was behaving as expected. When I tried to open it today it did nothing. I touched the spreadsheet, and just sat there. I tried other spreadsheets I have created, and they opened. I updated software to iCloud 2 days ago, and all has been well, except this glitch. I tried a soft reboot to the iPad, no success. I have an first. Gen iPad. Any suggestions? All help will be greatly appreciated!! My iPad is 16GB, with 12 GB free space. Thanks in advance. J.
