What Cocos2d-x/js version are you using for your other 2 games.

All games are using cocos2d-js v.3.10.

That is weird, do you get any logs in the console?

No. Just the submit message: 

08-16 11:21:53.554 15944-15944/bundle.name D/Google Play Services: Submit score 11 to CgkIk9WH46AaEAIQHg

Confirm the code its sending to

What do you mean?

I mean the id for your account that you use in the settings.

I’ve rechecked the id that i used in the SonarFrameworkSettings.xml and in the Google Dev Console, but nothing helps.

Try going through the setup process for Google Play again, I understand it’s annoying but something may have gone wrong during the setup process.

I've tried to reinstall Cocos Helper. I also release the game, thought that it would help, but error still remains. Furthermore my in-app purchases not working – "Authentication is required"

What system are you using for in-app purchase.

I found a problem. Somehow i insert the wrong SHA-key. I had to remake the game and use new SHA-key. After this Google Play Services work good.

Fantastic to hear you solved this.

If you have anymore questions don’t hesitate to ask,
