I just read all the post related to this topic but find no clear answer for Android devices. iOS users can use the "iCloud" option but I don't see that on my Android devices.
The situation is that I have an Android mobile with this game installed, a progress of about 180/260 missions and with all Heroes (except the new one, the demon) purchased. Yesterday I bought a Nexus 10 and after the table installed all the applications automatically (including HoD) I started the game. Sadly I found out that all the progress, coins and gems have been lost and what's more important, also the purchased Heroes.
So, I can accept loosing the progress, it's OK, I'm having fun with the game and can start it again. What I really need is a solution for the purchased Heroes.
Is there a way to fix this?
