Android Box SSO not logging out

Hi Team,
Recently we found an issue that, BoxSession.logout() api is not clearing the SSO cache. User can able to access the box files using SSO even though he logged out from Box. Could you let us know is there any api for clearing chaches?

1. Login Box using SSO
2. Enter email -> Submit -> Enter Username/Password -> Authentication success -> Able to access files
3. Logout Box using BoxSession.logout() -> Login again using SSO -> Enter Email -> Submit -> Entering into Box Files activity without asking the user credentials.
