Ooh, facebook... I can't know for sure, but that might be a reason. Since it's not linked to your G+ profile, you can't do the advert-id reset trick... I don't know if you can be logged in with a facebook AND a G+ account, but it might worth a try to see if it works with a google account. (Still while logged in with FB cloud save, restore to see if it works; log out, log in with google (hopefully it will keep your stats and data, don't know for sure [if it doesn't, log back to FB and cloud restore]), and reset the ad-id, then try.
