When you say, "previous version", what does that mean exactly? Version 3.6.1? I made very few changes between version 3.6.0 and version 3.6.2, so I would be very surprised if this issue is due to the updates. I would recommend backing up your library under Settings->Backup and Restore->Backup Library, uninstall MobileSheets, reinstall it, restore the library backup and then see if the issue persists. I want to rule out any issues due to a corrupted installation.
