Hi!
I'm using your controller and it's almost ideally matching my needs. Thank you very much for writing and sharing your work.
However I'm experiencing one problem and I was able to reproduce it on Demo solution from the repository.
Scenario is following:

1. Enable passcode (enabled by default in Demo app)
2. Deactivate app so it stays inactive.
3. Wait for passcode timeout
4. Activate app (either from task switcher or by tapping an icon) and see active lock screen
5. Do not enter anything and just kill the app.
6. Run the app from the icon
7. App runs and no lock screen shown.

Please let me know how this behavior can be fixed.
Thank you
