Hi, we have a trouble integrate Twitter Kit via Fabric for Unity.
We try to tweet App card by calling Twitter.Compose(), App card view will appear and image show correctly.
But when we press Tweet button, nothing happened and we got following error message from logcat on Android device. (for iOS device, Tweet failed too)
Unexpected response

We are using Unity 5.3.7f1, Fabric 1.2.4, Twitter Kit 2.0.2
Twitter API Key&Secret for api.twitter.com and the Key was approved for post tweet.
Once we have mentioned this trouble in another post NullReferenceException while calling Twitter.Compose() in Unity
Any suggestions?
