After setLockscreenVisibility(Notification.VISIBILITY_SECRET) the notification channel is still appearing on lockscreen

After set a notification channel to not show notifications at lockscreen, it still is showing the notifications on lockscreen.

notificationChannel.setLockscreenVisibility(Notification.VISIBILITY_SECRET);
notificationManager.createNotificationChannel(notificationChannel);

But after the creation of the channel I can debug it and see that the notification channel does not have the lockScreenVisibility set to VISIBILITY_SECRET (-1), it still has the default value, that is -1000.

notificationChannel.getLockscreenVisibility()

Does anyone knows how to set the lockscreen visibility to not show on lockscreen? Or have any idea why it is not being updated?

One more information is that I already have created the channel previously. But I have deleted and recreated the channel with the VISIBILITY_SECRET.

The documentation says that setLockscreenVisibility and setBypassDnd are "Only modifiable by the system and notification ranker."

The suggestion of @WillNewton works only after you have manually changed this settings.

The reason this may be happening is that even secret notifications are show on the lock screen if the lock screen is not secure (e.g. a PIN is not set):

When you delete and recreate a channel, all of the previous settings are restored. You must create a brand new channel (with a different channel ID) or completely uninstall/reinstall the app if you want to change anything other than the channel's name or description.
