Hi Kim,
I realize the inconvenience you are facing. Let me help you in answering the question.
I would like to inform you that new Windows 10 apps have permission to run in the background so they can update their live tiles, fetch new data, and receive notifications:
Follow the steps below and check:
- Open Settings or Press Windows + I keys
- Go to privacy
- Click on Background apps.
- locate the desktop app and slide it to off.
- You can do this for individual apps.
If you want to add app in the lock screen follow the below steps and check if it helps.
Step 1: Turn on notifications in PC Settings. (This should be on by default.)
- Open the Settings Charm.
- Tap or click Change PC settings.
- Tap or click Notifications.
- Slide the Show app notifications and Show app notifications on the lock screen switches to On.
Step 2: Add the app to lock screen notifications
- Open the Settings charm.
- Tap or click Change PC settings.
- Tap or click Personalize.
- In the right pane, with the Lock screen tab selected, under Choose apps to run in the background… tap or click one of the “plus” symbols and select the app.
Then under Choose an app to display detailed status, tap or click the icon beneath it and select the app.
Check if it helps.
