I looked at the log file. If the error your getting is only occuring for Amazon and not on your local phone, then this seems to be the same API_Key issue. Looking in your log file, I can see the API Key Decoder issues. If the system can’t decode the API, then it can’t initialize the Leaderboards which is what is causing the Nullreference exception.
As to a timeframe when this will be fixed, at the moment I can’t really say. While I developed the plugin, the API Key Decoder error is happening outside my plugin’s metaphorical jurisdiction. It’s occurring within the GameCircle SDK, while my plugin is merely trying to act as a middle-man between the Lua code and the Java SDK.
Still, I will keep this board up to date, but as of right now Amazon has not gotten back to me regarding this issue.
I am terribly sorry.
