Incremental achievement unlock callback not called

Services 3rd-Party
#1

Hello there,
I tried a lot to trigger this callback function but no luck.
When i call sdkbox::PluginSdkboxPlay::incrementAchievement(a,b)
callback function onIncrementalAchievementStep calls but when achievement unlocked,
there is no call for onIncrementalAchievementUnlocked or any error callbacks.
I can see that achievement is unlocked from Google Play Games interface. I can not reveal dependent achievement because of this.
Yet another thing is, i see lots of crash logs on google-play android vitals:

Thanks for your reporting.

Is it the first time newly unlocked?

no more log ?

Yes, it is the first time the achievement unlocked. It notifies that achievement unlocked but no call to onIncrementalAchievementUnlocked .
Unfortunately, i also have crashlytics integrated but this crash log is the one that gives most info.
