Amazon GameCircle not working in live testing environment

I'm trying to get the Amazon GameCircle to work for leaderboards and achievements.

Here's what I did:

1. I followed the instructions on how to create a game configuration by extract the md5 hash from the keystore. (I only have one keystore)

2. I used the game manifest provided by the unity gamecircle package and replaced the package name.

3. I downloaded the api_key.txt and placed it in the assets folder.

and I have security profile attached.

GameCircle works using the apk when I install it directly, but doesn't work when downloaded through the amazon app store.

Is there anything I forgot or anything else I could try?

here's the logcat messages regarding gamecircle:
