SetAchievement() always return false

[kkfrank2]

I use my appId, and GetAchievement() work right, but SetAchievement() and ClearAchievement() always return false.
But when I change appId to 480, there is no problems.
Is there some auth to my appId?

I use another appid, and there is no problem. have no idea what's wrong with my appid

Did you set the achievement write to GS or Offical GS?

If you set that to anything other than Client then your game client cannot SetAchievement ... cant recall if that will cause that method to return false or not but it definitely wont set the achievements.

Also make sure you publish, quote from the official docs on the topic.

This function returns true upon success if all of the following conditions are met; otherwise, false.
The specified achievement "API Name" exists in App Admin on the Steamworks website, and the changes are published.
RequestCurrentStats has completed and successfully returned its callback.
