I know there are lot of answers for this question ,i have tried all of them , i am still unable to find solution.
I have published the app on play store and now i am trying to add leaderboard in my game using google play services.I have added a new game in play store console(In Google Play Services Section) and completed all the steps.I have linked the app in console and it automatically authorize the game.After that i have added the tester account. i am using release build to test the game.But i am still getting this error "There is no linked app associated with this client ID"
I have tried deleting the linked app 3-4 times and added again as suggested in other answers.
I have added app id in my manifest file.
please suggest me if i am missing any step.
Thanks
Finally I resolved this issue by Re-Linking the Game for 3-4 times and added same game 2-3 times in the Linked Apps.I don't how it works but leaderboard is working fine now.
