That seems like a weird thing to be device-dependant. Maybe if it's the case, it might come from mismatched versions of software between users. Have you updated the game to the latest version (where WTTT is once again open?).

And are you really sure it's working? Are you able to download your Guest save and for it to display properly, not give an error (#3/4/5) or just give you your signed-in save?
