Must sign in over and over and over. – Box: The Content Cloud Review

Since iOS 11, I have had to sign back into the app every time it Is reopened. To be clear, if the app is not fully closed, there is no problem. But leaving the app open all the time defeats the extra security layer of Touch ID or an extra code. This behavior never occurred prior to iOS 11. Please fix!!!
