Impossible to set up? No unblock functions? – Number Shield Review

The app tells you to go to “Call Blocking & identification” within phone settings to activate it. This setting does it seem to exist. I went through every option in my phone settings and it’s just not there. I’m on 14.3. Also it does not say anywhere if the app can handle unblocking or if you have to do it manually from the blocked callers screen. Would be nice to make that clear. This would be useful if you’re blocking 10000 numbers at a time and you need to undo that.
