I have recently upgraded from a Fire 7 to a Fire 8. I had a game on my old device which I had progressed quite far in (and invested a few hours and a few £££). On the new device it seems I have to start over from scratch. According the unhelpful appstore response had that is it. - will have to start over. a bit gutted TBH.
It is not on gamecircle (whatever that is - never heard of it).
I am assuming there is no workaround possible to transfer my progress over. The App is there on my new device but not any progress.
