O jogo trava quando clico no botão de login, pois o jogo está no modo paisagem. Se eu usar o modo retrato, tudo funcionará bem e corretamente.

Eu recebi o seguinte rastreamento de pilha do bugsense quando recebi o travamento.

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.adssdk.plugins/com.facebook.unity.FBUnityLoginActivity}: java.lang.UnsupportedOperationException: Session: an attempt was made to request new permissions for a session that has a pending request.

Se algum de vocês tiver implementado isso no modo paisagem e não estiver travando durante o login, informe-me.
