Issues forcing apps to close on Android Devices.

Good afternoon all, sorry if this is the wrong place to post this, but I am looking for some advice.

Currently we are making the transition to Android tablets at my place of work. We are using Managed Home Screen to control what our users are able to use/view etc. Currently, if a user opens apps, while signed into the managed home screen, we are unable to force them to close when the user signs out. This causes a lot of issues for us as we can't have users being able to see what the previous user has been on, or have them signed in to any webapps that they were on.

Any help/advise would be appreciated.

TLDR; Looking for a way to have apps automatically close when a user logs out of Managed Home Screen.

Thanks
