I have tried it on my old iphone and my Note 3. I have logged out and back in. I have uninstalled smartthing app and reinstalled. But everytime I try to add the shortcut to dashboard then click Auto import and then pick the switches. When I click next, a red banner appears that says "Error:An unexpected error occurred"
The link from actions full name is “Add shortcuts for groups or individual light switches on your dashboard and tap them any time for easy control”
