IOS Achievements not unlocking

Hello,
I have a problem unlocking achievements on IOS with "Social" class.
I try to use Social.ReportProgress but nothing happens (opposed to Android - which there everything work fine).
The same for incremental and normal achievements.

I looked at similar threads and used the GKAchievementReporter. It seems it fixed the problem for everybody, but not for me.
The problem happens in sandbox and production as well.
I know that connection to Game Center is established as leaderboard is working fine.

this is the code:

Code (CSharp):

1. //                        Social.ReportProgress (achievement100LessInTheAir, (enemyPlanesDestroyed / 100D) * 100D, null);
2. //                        Social.ReportProgress (achievement500LessInTheAir, (enemyPlanesDestroyed / 500D) * 100D, null);
3. //                        Social.ReportProgress (achievementClearSky, (enemyPlanesDestroyed / 2000D) * 100D, null);
4.  
5.                         GKAchievementReporter.ReportAchievement (achievement100LessInTheAir, ((float)enemyPlanesDestroyed / 100f) * 100f, true);
6.                         GKAchievementReporter.ReportAchievement (achievement500LessInTheAir, ((float)enemyPlanesDestroyed / 500f) * 100f, true);
7.                         GKAchievementReporter.ReportAchievement (achievementClearSky, ((float)enemyPlanesDestroyed / 2000f) * 100f, true);
8. //                      
9. #endif
10. //                        Social.ReportProgress (achievementSurvivor, (PlayerPrefs.GetFloat ("BestTime", 0) >= 120) ? 100d : 0, null);
11. //                        Social.ReportProgress (achievementTheUltimateSurvivor, (PlayerPrefs.GetFloat ("BestTime", 0) >= 300) ? 100d : 0, null);
12. //                        Social.ReportProgress (achievementWelcomeBackCannoneer, (PlayerPrefs.GetInt ("LevelReached", 1) > 1) ? 100d : 0, null);
13. //                        Social.ReportProgress (achievementFireBreath, (PlayerPrefs.GetInt ("RedDragon", 0) == 1) ? 100d : 0, null);
14.  
15.                         GKAchievementReporter.ReportAchievement (achievementSurvivor, (PlayerPrefs.GetFloat ("BestTime", 0) >= 120) ? 100f : 0, true);
16.                         GKAchievementReporter.ReportAchievement (achievementTheUltimateSurvivor, (PlayerPrefs.GetFloat ("BestTime", 0) >= 300) ? 100f : 0, true);
17.                         GKAchievementReporter.ReportAchievement (achievementWelcomeBackCannoneer, (PlayerPrefs.GetInt ("LevelReached", 1) > 1) ? 100.0 : 0, true);
18.                         GKAchievementReporter.ReportAchievement (achievementFireBreath, (PlayerPrefs.GetInt ("RedDragon", 0) == 1) ? 100f : 0, true);
19.  
20.  
21.                         int threeStars = StoreManager.Instance.SumLevelThreeStars ();
22.  
23. //                        Social.ReportProgress (achievementAhui1, threeStars >= 10 ? 100d : 0, null);
24. //                        Social.ReportProgress (achievementAhui2, threeStars >= 20 ? 100d : 0, null);
25. //                        Social.ReportProgress (achievementAhui3, threeStars >= 30 ? 100d : 0, null);
26.  
27.                         GKAchievementReporter.ReportAchievement (achievementAhui1, threeStars >= 10 ? 100f : 0, true);
28.                         GKAchievementReporter.ReportAchievement (achievementAhui2, threeStars >= 20 ? 100f : 0, true);
29.                         GKAchievementReporter.ReportAchievement (achievementAhui3, threeStars >= 30 ? 100f : 0, true);

Hope someone can shed some light what am i doing wrong.

Thank you,
Lior.
