I have recently installed Fire Emblem Heroes on my iPad. After discovering that it wouldn't run on my aging iPad Mini, I reinstalled it on an Android emulator and started playing it on PC... only to discover that my Orbs (the main currency of the game) were not transferred from one platform to the other, even if both were linked to the same Nintendo account.
The explanation I read on forums were that no game does that, since that would imply that money 'put' on the Apple AppStore could be 'payed' by the Google store (and vice-versa). So the characters and other stuff I have are there on both platforms, but the Orbs I earn are either on one or on the other.
Could this be the problem that keeps us from having a unique Pathfinder account across all platforms (Android, iOS and futurely PC)? Maybe we could have all the cards, characters and adventures on every platform but have the money and chests separated in each one? That would be good enough for me...
