Hello,
I can't get my app to list (or unlock) any of the achievements set in Google Play Game services. The app is linked, the achievements are public and everything seems to be in order in the Google Play console. But when the list or metadata for achievements are called, all I get is "Cannot read property 'page' of null"
Here is the event sheet for the achievements part. Has anyone seen this error before? Searching google play development help didn't help.
