Well I don't know if mine had said it on the lock screen or not. I just tried it again for a reminder for 6:30. What I should clarify is if I set it in the Keep app my phone vibrates or makes a sound and my Gear S2 even gives me a notification showing my reminder. When set through the assistant it almost seems like it is a silent reminder which is not what I am looking for. I am really wanting it to give me a sound or vibration and stay there so I actually get reminded and I know I can do it manually through Keep but it would be nice to be able to just tell the assistant to remind me at a time and have it actually remind me.
