Open menu and there's a button for upload sync bro then screen shot that code and open the 4.5 and open menu again and download sync then type code you're done.
I saw that, but requires a sync code, which I don't have.
You can get your sync code when you load your current save in the original app, then open the menu and look for upload sync.
Head to the new app and then press the main menu and download the sync.
Thanks. 👍
