Since the last beta update, I can no longer completely close this app. It runs in the background, which is unacceptable. I click on NO to run in the background, and the app doesn't close. If I click on the Android home button or back button, they don't close the app. I can only click on the Force Stop button to close this app. For security reasons, I want this app to close completely and require a password to reopen it. Please fix. Thank you.
