Hey Apple,
My team is running into an issue where we have updated achievements in App Store Connect portal but these updates are not being seen in Game Center on device while playing. We've both edited existing achievements, removed old ones, and added new ones yet none of them seem to be reflected in game; only the changes made up to a certain point have applied despite us not having changed anything about our methods of authoring/editing these in our code or the portal.
We're still in development so none of our achievements have been published to Live and we've tried using a brand new apple id user to see if somehow Game Center was incorrectly caching the old achievement data; even with the new user it was only showing the old achievement info.
Wanted to reach out as we've exhausted all troubleshooting options and this issue is blocking us from verifying our achievements.
Images attached highlighting this issue in the form of discrepancy in total achievements shown in game center on device vs our app store connect portal.
