How come I can't add switch at this time

Why is it then certain smart apps that ask for a switch says I can’t do this at this time as if I don’t have it. I’ve made virtual switches, buttons and other ide modifications but don’t understand why I can’t add things like that or why I don’t have them or where to get them. There’s a lot to this stuff. Like I can’t use the ridiculous garage door app because it says I can’t add some switch. What’s that mean

Are you certain your Things exist under My Devices in the proper Shard for your Account?

This mismatch is unlikely except for devices manually added in the IDE.

Check your Shard…
