Blank the screen right after leaving the app
Not sure how to phrase the title better.
What happens is that the OneDrive app is password protected with Touch ID. When I leave the app and then return to it again after some time, OneDrive takes some time to bring up the Touch ID alert. In the meantime, I am able to see the last screen when I left OneDrive with all the contents visible. My suggestion is to either quickly bring up the Touch ID alert or blank the screen background while we wait for the alert to come on.
