If you install MobileSheets under two different accounts, my advice is still relevant - just backup the library on one account and restore that backup on the other account. Or you can sync the cloud and sync MobileSheets on both accounts to the same cloud folder. Alternatively, you can go to Settings->Storage, change the storage location on each account to the same folder, and also check the option to "Expose Database". This needs to be a folder in internal storage (not on an SD card). Then MobileSheets will share the same files and database for both accounts.
