This app was way better before.However, there are ways to get around this limitation using additional apps and techniques during setup.

Multimedia: Send and receive photos, videos, documents, and Voice Messages.There are only options on lock screen to 1) see the sender and message 2)see the sender and hide the message 3) do not see the notification at all.

When a person is blocked in the app, they are not explicitly notified.Once the app is set up on a device, there is no login process.
