Leaderboard issue - no one can see my leaderboard but me?

Hi everyone.

I released my game on the app store and had about 25 friends download it. The problem is that no one can access the leaderboard.

For everyone it shows "No Data Available".. however on my device I can see everyone highest scores on the leaderboard and it's working just fine.

Am I missing a setting somewhere that enables this for everyone and not just my (developer) account?

 

Check in iTunes connect that the leader board is live.?

 

Yup it shows that its active
