You said you set up cloud sync - can you please verify that you are using the Sync Library->Synchronize to a cloud folder option in MobileSheets, and not just a file-based sync outside MobileSheets? Can you also verify that you are pushing changes from the primary device with the sync type set to "Update Folder", and pulling down changes to the secondary device with the sync type set to "Update Device"?
