We have implemented EGS Achievements for the title we are currently working on. Achievements are unlocking correctly in-game and achievement progress is displayed correctly in the in-game overlay (Shift + F3).
However, the achievement count on the EGS Library page always shows 0 achievements unlocked, regardless of the actual number of achievements unlocked. This issue exists for builds in both the Dev and Staging sandboxes.
My current assumption is that this will work correctly once the achievements are pushed to the Live environment. We have a released title where the count is updating correctly.
Can anyone confirm this assumption?
