I had set up a few groups (e.g., Living Room, Office, etc...) that had all of the lights/switches for those rooms. They worked perfectly. However, there appears to be an active issue between Echo and SmartThings, and as part of my troubleshooting that issue, I "forgot" all my devices and then "re-discovered" them. Now, when I go into the Groups section, it is blank. But the commands still work, and I can't edit the groups. For example, I wanted to add something to my Living Room group, but it doesn't show up in my Groups section, and I can't create a new group with a Living Room name because it says a group already exists. Any thoughts?
