I purchased the license for Poweramp to install it on my FiiO M6 device, I downloaded the Poweramp-2.0.10-build-588-uni.apk version and successfully installed it on my device, so I did the Already Purchased procedure on the inserted email software and Order ID, but Poweramp keeps telling me "Validate purchase failed - No Google or Email account (Android 3+) registered on the device"
The version is in Italian and the device is connected to the internet and has no Google Play
I would like to make the software work otherwise, if it is not possible to recover the money spent.
