+  - Rename `SessionStatus#LoadingFromStorage` to `SessionStatus#Initializing`
+  - Rename and refactor `SessionStatus#NetworkError` to `SessionStatus#RefreshFailure(cause)`
+    *Note: The cause can be either `RefreshFailureCause#NetworkError` or `RefreshFailureCause#InternalServerError`. In both cases the refreshing will be retried and the session not cleared from storage. During that time, the session is obviously not usable.*
