Can't get notifications to work on app

Tags: #<Tag:0x00007f73acaf4188>

I know I am probably missing something really basic. I can’t get the service to show up in my list of services. I want to send notifications to my phone through the HA app. I can’t find a real basic, baby level, walk-through of exactly what to do. I also don’t know where to find my mobile ID. Any help would be appreciated, :blush:
