Why do I no longer get interactive notifications?

[fleapower]

My wife and I have Moto G's (4.4.4 on Cricket). Got them about a week ago. When we first got them, we could snooze our calendar alerts, reply and archive emails, and do other app related tasks directly from our notifications. Now, our notifications don't do anything but notify. Did we change a setting somewhere? Do some apps screw up notifications?

Thanks!
