Issue: You have a company iPad or Android tablet. User1 has registered and used the tablet with the company and then left the company. You deregister User1 and then reassign the tablet to User2. After User 2 registers the tablet and tries to access an appmark, they get an error of expired session.
Solution: The user must try the appmark a second time and then they can access the resource. The reason for this is a cookie still exists for User1, who no longer is valid. The second attempt replaces the cookie with a valid cookie for User2.
