Google play leaderboard only works on 1 account

I am currently working on a leaderboard for my game and everyt$$anonymous$$ng works fine except when I tried to change account it says somet$$anonymous$$ng like: 'No leaderboards for t$$anonymous$$s game' The first account I used to try the leaderboard with works. Btw: it is an internal test and both the accounts are added, i haven't tried it in a normal published version. Does anyone know how to fix t$$anonymous$$s, or maybe it is a bug?
