### Describe the bug

First problem:

After creating a shortcut for already **freezed** app (long press 'Freeze/unfreeze' button) and setting up 'Open app after unfreezing' and 'Automatically freeze app when the phone is locked' the shortcut is placed on home screen but the icon is darker then it supposed to be, and gets completely black when the app is freezed after locking and unlocking phone (when 'Automatically freeze app when the phone is locked' is triggered)

Second problem:

'Automatically freeze app when the phone is locked' trigger works only for the first time and fails to freeze app after first 'lock/unlock' cycle leaving 'Waiting for the phone to be locked...' active despite further locking and unlocking the phone.
