Good afternoon how are you?
I tested the example "example_ cordovagame_increment achievement required id"
See the error:
Login error:

can you help me?
Thank you very much in advance.

Hi,

You need to test signed apk.

Game plugin work with only signed apk (alpha, beta, or normal)

See following instruction: https://github.com/cranberrygame/cordova-plugin-game#test
