Anyone else had problems with the android key on Cocoon?

I'm asking this here in case nobody could answer me on the Cocoon boards: I tried to publish a game on the googleplay store but I can't upload the app because it says it doesn't have my personal signing. But I'm sure I used the apk signer to create a keystore file to add it to the game on the Cocoon site before building the project. Anyone else experienced the same problem?

i use cocoon.io and i never face like that problem. maybe you compile with the wrong keystore ? also try to setup all things from the first step or with another game and see if the problem still exist.

make sure under keystore signing you have android selected and the proper keystore selected i use keystore explorer to build the key
